ct-bugcheck: Add tools to poll for and report ath10k firmware crashes.

This tool can periodically check for ath10k firmware crashes.
If it finds a crash, it will package up the binary crash dump,
some OS level things like dmesg, lspci, etc into a tar file.

It then notifies the user about the crash and asks them to report
the bug to the appropriate email address.

This is most useful when used with ath10k-ct driver and
CT ath10k firmware, but it should also report issues with stock
ath10k driver and firmware in case one has appropriate contacts
to debug them.

This tool could be extended later for other modules/bugs/etc.
