[LTP] [PATCH v2 2/3] lib: TCONF on "not supported" errnos in SAFE_SOCKET()

[Petr Vorel]

*NOSUPPORT errnos likely mean there is configuration issue rather than
test failure.

e.g. missing dccp module in netstress.c which was so far set as TBROK:
safe_net.c:117: BROK: netstress.c:654: socket(10, 6, 33) failed: ESOCKTNOSUPPORT
