With upcoming BZ#12683 fix, syscall cancellation is not more handled
by {libc,pthread,librt}_{enable,disable}_asynccancel symbols. This renders
both LIBC_CANCEL_HANDLED and empty declaration and tst-cancel-wrappers.sh
unrequired. This patch removes both the macro and the nptl test.
Checked on x86_64-linux-gnu.

Continuing the removal of unused __libc_* function names, this patch
removes the __libc_pselect alias.
Tested for x86_64 that installed stripped shared libraries are
unchanged by this patch.
* misc/pselect.c [!__pselect] (__libc_pselect): Remove alias.
* sysdeps/unix/sysv/linux/pselect.c [__NR_pselect6]
(__libc_pselect): Likewise.
