- Replace all users of `$(RIOTBASE)/build` with the already present

With the new version some OpenWSN modules are optional:
- openwsn_cjoin (and therefore opewnsn_coap)
- openwsn_6lo_fragmentation
- openwsn_icmpv6echo
- openwsn_crypto
- openwsn_udp (optional but kept as default)
New optional modules have been added:
- openwsn_iee802154e_security (link layer security)
- openwsn_adaptive_msf (MSF dynamic slot allocation)
Openvisualizer needs to be updated to be compatible with the new
version.
