libsm: remove dependency on e2fsprogs

This patch is to solve the following circular dependency problem.

     systemd -> dbus -> libsm -> e2fsprogs -> util-linux -> systemd

libsm doesn't have any dependency on e2fsprogs. It might be some dependency
on util-linux's libuuid, controlled by configure options. So e2fsprogs should
be removed from the DEPENDS variable.

Ideally, we should add a PACKAGECONFIG for 'libuuid' for libsm. However, if
libsm depends on util-linux, we would have the circular dependency described
above. That's why this patch explicitly set '--without-libuuid' in EXTRA_OECONF.
libsm would still be working well because it would fall back to an internal
algorithm to do the uuid stuff.
