[PATCH] run-command: async_exit no longer needs to be public

Hi Lars,

If you need to re-roll your 'ls/filter-process' branch, could you please
squash this into the relevant commit c42a4cbc ("run-command: move check_pipe()
from write_or_die to run_command", 20-09-2016).

[Note that commit 9658846c ("write_or_die: handle EPIPE in async threads",
24-02-2016) introduced async_exit() specifically for use in the implementation
of check_pipe(). Now that you have moved check_pipe() into run-command.c,
it no longer needs to be public.]

Thanks!

ATB,
Ramsay Jones
