multimedia/zoneminder: fix build on armv7 (again)

After pkubaj@ fixed armv7 support in ports commit 5094662, the fix was
upstreamed.  Unfortunately upstream made a mistake in processing the
patch, leading to broken code on armv7.  This was subsequently fixed in
the linked commit, but has not made its way into the ports tree yet.

Fix the build once again by importing the patch from the commit above.
