build: Improve --with-system-libc support.
* build-aux/build-lib.sh: Avoid building libc for --with-system-libc.
Make libmes richer.
build-aux/check-mescc.sh: Enable 50-malloc test.
* include/dirstream.h: Use HAVE_DIRSTREAM_H to cater for non-existing
dirstream.h.
* include/grp.h[SYSTEM_LIBC]: Typo.
* include/mes/lib.h (__brk, __call_at_exit)[SYSTEM_LIBC]: Declare.
* include/stdlib.h (comparison_fn_t)[SYSTEM_LIBC]: Declare.
* include/time.h (mktime): Return time_t.
* lib/posix/isatty.c [SYSTEM_LIBC]: Do not (re)declare termios.
* lib/stub/mktime.c (mktime): Return time_t.
* lib/tests/scaffold/41-ternary.c (main): Remove assumption that
locals are initialized.
* lib/tests/scaffold/70-stdarg.c: Cater for SYSTEM_LIBC.
* lib/tests/setjmp/80-setjmp.c: Declare jmp buf.
* lib/*/*.c: Add missing mes/lib.h, errno.h includes.
