Move MK_REPRODUCIBLE_PATHS to bsd.opts.mk

In commit faeaa25f56 MK_REPRODUCIBLE_PATHS was introduced, but some
ports that include bsd.debug.mk then started to fail with:

    make: /usr/share/mk/bsd.debug.mk:19: Variable "MK_REPRODUCIBLE_PATHS" is undefined
            in /usr/share/mk/bsd.lib.mk:525
            in /wrkdirs/usr/ports/devel/libsysinfo/work/libsysinfo-0.0.3/Makefile:16
    make: Fatal errors encountered -- cannot continue

This is because bsd.debug.mk includes bsd.opts.mk, not src.opts.mk. Move
the MK_REPRODUCIBLE_PATHS option to bsd.opts.mk to fix this.
