3635004dcd libs/libc/grp: fix getgrbuf_r() pointer-alignment padding
padlen = sizeof(void *) - (addr % sizeof(void *)) never returns 0, even
when addr is already pointer-aligned -- it returns a full alignment unit
instead. Since callers size buflen for zero padding, the subsequent
"buflen < padlen + reqdlen" check then always fails, so getgrgid()/
getgrnam() and their _r variants always return ERANGE.

Found via `id` on sim:toybox, which resolves gid 0 to "root" through
this path.
