rootfs.py: Check for LDCONFIGDEPEND being empty string

We override LDCONFIGDEPEND to be empty string for uclibc
however the current check is for it being None as a result
the function is still executed but ldconfig-native is not
built as dependency for rootfs when building with uclibc

Fixes errors like below

File:
'/home/kraj/work/angstrom-repo/sources/openembedded-core/meta/lib/oe/rootfs.py',
lineno: 191, function: _run_ldconfig
     0187:    def _run_ldconfig(self):

     0189:            bb.note("Executing: ldconfig -r" +
self.image_rootfs + "-c new -v")
     0190:            self._exec_shell_cmd(['ldconfig', '-r',
self.image_rootfs, '-c',
 *** 0191:                                  'new', '-v'])
