[PATCH 1/3] Remove useless #ifdefs from sysdeps/unix/sysv/linux/sigprocmask.c

[Yury Norov]

The sysdeps/unix/sysv/linux/sigprocmask.c includes nptl-signals.h
via nptl/pthreadP.h, and so SIGCANCEL and SIGSETXID become defined
unconditionally. But later in the code, there are some checks weither
symbols defined, which is useless. This patch removes useless checks.

	* sysdeps/unix/sysv/linux/sigprocmask.c: Remove useless #ifdefs
