A year or so ago I added a mach binary/bootstrap/package to the tests.zip. The idea was to make it easier to run test harnesses without a srcdir (i.e in a test machine). The effort kind of petered out, and changes like the multiple tests.zips broke it.

But now we have a solid workflow for debugging on remote instances, and the mach in the tests.zip work is once again important. This bug will just fix it up back to a working state.
Currently the mach binary will look for 'mozinfo.json' and if it finds it assume
we are in an objdir. But now, 'mozinfo.json' can also be found in an extracted
tests.zip (depending which zips were used). This trips up the tests.zip mach
environment and causes some problems.

This works around the issue by looking for both 'mozinfo.json' and 'config.status'

This makes sure mozharness will always extract the mach binary and it will
be available when debugging interactive loaners.

This is a bit of a hodge podge of small fixes that I needed to run |mach mochitest|
on an interactive worker. Included:

1) Add some packages to SEARCH_PATHS that mochitest needs
2) Always add SEARCH_PATHS even if mach package is found
3) Don't try to register commands that don't exist (i.e it was in an unused test zip)

Nit: there is a double space in here.

I don't exactly understand the changes but I don't see anything obviously wrong.

Are any changes for mobile required?

Possibly, but those would be out of scope for this bug. This patch is basically about getting |mach --help| to work (none of the actual test commands will work after this lands). I need to file follow-up bugs (one per test harness) to get each test harness working individually. Even then I'm not sure I'll want to tackle mobile+desktop at the same time, I'm not really sure how much extra work (if any) mobile will be at this time.
