tests/stdin: refactor test application

Browse Source 
The test application now prints in a loop the input character. In case
stdin is not ready yet after startup this lets the possibility to try to
send several time a character before failing.
The automatic test is now more robust on platforms where stdin takes
time before it gets in a ready state (some AVR, hifive).
