Move some chown / lchown / fchown definitions to syscalls.list (bug 14138).

Browse Source 
Continuing the move of syscall definitions to syscalls.list, where the
removal of support for old kernel versions has made this possible,
this patch moves various definitions of chown, lchown and fchown.

In most cases the need for special syscalls.list entries (rather than
existing generic ones) is because these architectures use chown32,
lchown32 and fchown32 as syscall names.  Some architectures also have
symbol versioning compatibility for older versions of chown having
been equivalent to lchown.

In the case of powerpc, chown.c (providing the chown@@GLIBC_2.1
default version) is replaced by a syscalls.list entry (for powerpc32;
powerpc64 has no need for this because of its more recent minimum
symbol version, so can just use the entry in
sysdeps/unix/syscalls.list), but lchown.S is left as-is because it
provides the compat version of chown as an actual alias for __lchown,
which is not yet supported by syscalls.list.  This file can be removed
once such aliases are supported in syscalls.list.
