Subject: [PATCH] Makefile: fix race if we run `make update-mocks` in a clean
 tree.

    /bin/sh: 1: ccan/ccan/cdump/tools/cdump-enumstr: Text file busy
    make[1]: *** [common/Makefile:81: common/gen_htlc_state_names.h] Error 2
    make[1]: *** Waiting for unfinished jobs....

The fix is to make sure all generated headers are made first, and
thus cdump-enumstr.
