Subject: [PATCH] tools/nolibc: fix spelling of FD_SETBITMASK in FD_* macros

While nolibc-test does test syscalls, it doesn't test as much the rest
of the macros, and a wrong spelling of FD_SETBITMASK in commit
feaf75658783a broke programs using either FD_SET() or FD_CLR() without
being noticed. Let's fix these macros.
