package/refpolicy: ensure REFPOLICY_EXTRA_MODULES_DIRS is empty when it should be

Browse Source 
When both BR2_REFPOLICY_EXTRA_MODULES_DIRS and
PACKAGES_SELINUX_EXTRA_MODULES_DIRS are empty, we expect
REFPOLICY_EXTRA_MODULES_DIRS to also be empty. However, due to spaces,
this is not the case. This commit adds a $(strip ...) call to ensure
it is the case.

Thanks to this, the check on whether REFPOLICY_EXTRA_MODULES_DIRS is
empty later on will really work as it should.
