jujud binary version check error

[dosaboy]

I'm hitting the following sometimes:

It's because the sosreport is from aarch64 (ARM), which obviously won't run x86-64.

W're attempting to exec juju --version to get the version which won't be possible.

We can probably get the info by reading the binary.
