rS294515: Fix the implementations of PSEUDO_NOERROR and PSEUDO.

Summary

The PSEUDO* macros should not declare <syscall>, only _<syscall> and
__sys_<syscall>. This was causing the interposing C wrappers to be
ignored due to link order.

Without this change, threaded applications don't use mutexes around system calls and threaded programs likely do not work correctly.

Mostly, it was not about mutexes but for working cancellation. It is more complicated for signal-related syscalls, esp. sigaction(2), where the bug could result in non-functional rtld locks.
