Fix [1] is introducing another problem in that memset is added twice to
the libc makefile when OVERRIDE_LIBC=1 (the C and asm implementations).
Correct by adding memset.c when OVERRIDE_LIBC=0 and memset.S when
OVERRIDE_LIBC=1.

Change [1] introduced the memcpy_s function and added the source file to
lib/libc/libc.mk but omitted to update lib/libc/libc_asm.mk
Arm platforms (and platforms from one partner) use OVERRIDE_LIBC=1
option as a platform default hence consume libc_asm.mk
To prevent this confusion to happen again, create libc_common.mk for the
common set of C files to build.
libc_common.mk is included by both libc.mk and libc_asm.mk
The latter adds asm implementations of libc functions.
