powerpc: Fix powerpc64 strchrnul build with old gcc
The compiler might not see that internal definition is an alias
due the libc_ifunc macro, which redefines __strchrnul. With
gcc 6 it fails with:
In file included from <command-line>:0:0:
./../include/libc-symbols.h:472:33: error: ‘__EI___strchrnul’ aliased to
undefined symbol ‘__GI___strchrnul’

Use libc_ifunc_hidden as stpcpy. Checked on powerpc64 with
gcc 6 and gcc 13.
