Consolidate set* Linux implementation

This patch consolidates the Linux setegid, seteuid, setgid, setgroups,
setregid, setresgid, setresuid, setreuid, and setuid implementation on
default sysdeps/unix/sysv/linux/set*.c implementation.  It basically
removes all the architecture define implementations and add support for
__NR_set*32 syscall on Linux default implementation.

Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
