Break out the inclusion of the operating-system-specific Makefile into

a separate emulator-opsys.mk file.

The emulator-opsys.mk file defines EMUL_DISTRO and the various *EMUL*DIR*
variables, as well as any opsys-specific variables.

Include this file within compat_netbsd/Makefile.common so that the
*EXEC_FMT variables (defined by the compat*/emulator.mk files) are
defined.  This fixes the build of compat* packages.

XXX emulator-opsys.mk will go away in the near future as we do more
XXX appropriate information hiding.
