target.mk: further improve handling of default enabled SECCOMP

The fix in commit 847fad476f3d ("target.mk: improve handling of default
enabled SECCOMP") unfortunately does not work for targets where the ARCH
variable is set in ./$(SUBTARGET)/target.mk.

To get this working, the ./$(SUBTARGET)/target.mk must be included
before the check.
