Jeff Hostetler dd77cf61a1 help: include fsmonitor--daemon feature flag in version info 
Add the "feature: fsmonitor--daemon" message to the output of
`git version --build-options`.

The builtin FSMonitor is only available on certain platforms and
even then only when certain Makefile flags are enabled, so print
a message in the verbose version output when it is available.

This can be used by test scripts for prereq testing.  Granted, tests
could just try `git fsmonitor--daemon status` and look for a 128 exit
code or grep for a "not supported" message on stderr, but these
methods are rather obscure.

The main advantage is that the feature message will automatically
appear in bug reports and other support requests.

This concept was also used during the development of Scalar for
similar reasons.

# to fail because file is supposed to be unreadable after a successful
# chmod. In an environment (i.e. combination of what filesystem is
# being used and who is running the tests) that lacks SANITY, you may
# be able to delete or create a file when the containing directory
