patman: Support absolute and ~user-relative alias files
Python doesn't naturally support tilde (~) as a user-home marker in
paths, but git-config does. So we need to resolve it before continuing.
We also shouldn't blindly join the top-level tree with the aliasesfile
path, because it might be an absolute path.
This resolves warnings like the following:
Warning: Cannot find alias file '/path/to/source/tree/~/.git-email'
Seen when git-config is like:
$ git config sendemail.aliasesfile
~/.git-email
