[meta-selinux][PATCH] refpolicy_common: strip POLICY_CUSTOM_BUILDOPT before passing to make

POLICY_CUSTOM_BUILDOPT is passed directly to the refpolicy make command
as CUSTOM_BUILDOPT. When layers use ':append' to extend this variable
(e.g. POLICY_CUSTOM_BUILDOPT:append:distro = " option"), BitBake
introduces a leading space. Passing that raw value to make causes:

  make: *** No rule to make target 'option'.  Stop.
