Add support for alternate keychains in expression.

[jaraco]

• Add test capturing need for an alternate keyring with an alternate keychain.
• Add support for getting another Keyring with an alternate keychain. Fixes Allow keychain to be specified in macOS #579.
• Update changelog.

With this change, one can now easily select the relevant keychain thus:

keyring.get_keyring().with_keychain('~/Library/Keychains/alt.keychain-db').get_password(...)

And one can re-use that alternate keychain path with:

alt = keyring.get_keyring().with_keychain('...')
alt.set_password(...)
alt.get_password(...)

This is _very_ welcome to us MacOS users.

This also solved #571 in a much more elegant manner than i proposed.
