build: fix libcap configure flag handling
* m4/jm-macros.m4 (coreutils_MACROS): The code to handle configure-time
enabling or disabling of libcap support was broken. It would treat any
libcap configure option as --disable-libcap because it doesn't check
$enableval at all. This change makes sure we do the sane thing:
--disable-libcap -> disable and don't run any tests
--enable-libcap -> run tests and fail if not found
default -> run tests and warn if not found
