Default MK_META_MODE per MK_DIRDEPS_BUILD

[sjg]

Summary

Also update to latest dirdeps.mk so we can

make -f dirdeps.mk some/dir.${MACHINE}

ie priming DIRDEPS from command line.

Might this conflict with something? The WITH_META_FILES was known to be "not the normal meta build" so I worry it might break the dirdeps build in weird ways now.

I don't think so, with the new knobs I think - and therefor the idea is to consider MK_META_MODE a subset of MK_DIRDEPS_BUILD.
Very few parts of the build (outside say sys.mk) should really care about the distinction. The idea is that most places in the build could simply consider MK_META_MODE.

The idea here is that if meta mode is enabled - (via MK_META_MODE or MK_DIRDEPS_BUILD) some things can be done differently - eg. use of META_COOKIE_TOUCH

If we treat MK_META_MODE as a subset of MK_DIRDEPS_BUILD, then makefiles can simply consider MK_META_MODE.
On very rare occasions it may be necessary to check MK_META_MODE==yes and MK_DIRDEPS_BUILD==no

Yes this sounds good. The only place I found with a possible conflict is already handled fine (top of sys.mk).
