On error Jlink exits with a no error code by default.
From the JLink User Guide:
'-ExitOnError' has the same meaning as the 'exitonerror' command
'exitonerror' command
This command toggles whether J-Link Commander exits on error or not.
1: J-Link Commander will now exit on Error.
0: J-Link Commander will no longer exit on Error.
Executing 'flash/reset' without a board connected now correctly returns an
error. For 'term' it does not show an error due to the way it is handled
internally.
It also returns an error when the board fails to do an operation when it
is in a state where it cannot be flashed for example.
This commit rewrites the example so that the registration loop is
run inside the main() function instead of running the standalone
submodule of epsim. It also adapts the example application to
parse the RD UDP endpoint locally and provide this to epsim's
register() function.
xSemaphoreTakeRecursive() returned before the fix: pdFALSE(equal to pdFAIL) when the call was successful in obtaining the semaphore
and pdTRUE(equal to pdPASS) when the call did not successfully obtain the semaphore.
According to freertos documentation:
"pdPASS Returned only if the call to xSemaphoreTakeRecursive() was successful in obtaining the semaphore"
"pdFAIL Returned if the call to xSemaphoreTakeRecursive() did not successfully obtain the semaphore."
Fixed it to return the correct value.

Added test for freertos. Only for BOARD:esp32-wroom-32 at the moment.
At the moment it only tests xSemaphoreTake(), xSemaphoreTakeRecursive() and the creation of the semaphore.
It creates the semaphore and calls take for it multiple times and checks whether the return value is correct.
Take should return (quote freertos documention):
"pdPASS Returned only if the call to xSemaphoreTakeRecursive() was successful in obtaining the semaphore."
"pdFAIL Returned if the call to xSemaphoreTakeRecursive() did not successfully obtain the semaphore."
The same for xSemaphoreTake().
The future goal for this test is to test the complete freertos compatibility layer
and to have the test for a general freertos compatibility layer that does not only work for esp32.
Also remove binding of the DNS server to 2001:db8::1. It causes
`dnsmasq` to send router advertisements from that address, which is
not a [valid source for RAs][RFC 4861], so a default route is never
configured on the RIOT to reach the DNS server.
