Revert "configure.ac: fix pkg_check_modules calls"

CFLAGS and LIBS are variables that users are entitled to modify in order
to compile the package, so do not tamper with CFLAGS and LIBS.

COM_ERR_CFLAGS, EXT2FS_CFLAGS, DBUS_CFLAGS, LIBNL3_CFLAGS, TIRPC_CFLAGS,
COMM_ERR_LIBS, EXT2FS_LIBS, DBUS_LIBS, LIBNL3_LIBS, and TIRPC_LIBS
should be used directly where appropriate and apparently they already
are.

This reverts commit b54d97d677481287faa5d6b98c92f111141c1af3.
