1944714 - `mach repackage pkg` Fails when run locally on macOS due to "Exception: Could not find xar tool"

Status: NEW

(Release Engineering :: General, enhancement)

Description

[Haik Aftandilian [:haik]]

Sometimes developers have a need to build the macOS pkg locally. We should update mach repackage pkg to work locally on macOS. At present, the command fails with the error message below.

$ ./mach repackage pkg -i nightly.tar -o foo.pkg
Error running mach:

    mach repackage pkg -i nightly.tar -o foo.pkg

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke ``./mach busted`` to check if this issue is already on file. If it
isn't, please use ``./mach busted file repackage`` to report it. If ``./mach busted`` is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

Exception: Could not find xar tool.

  File "/Users/haik/r/mc/python/mozbuild/mozbuild/mach_commands.py", line 2487, in repackage_pkg

mach repackage is more or less owned by releng AFAIK.
