[PATCH] Drop deprecated/unused crypto.gpg_path

[Daniel Kahn Gillmor]

crypto.gpg_path was only used when we built against gmime versions
before 3.0.  Since we now depend on gmime 3.0.3 or later, it is
meaningless.

The removal of the field from the _notmuch_config struct would be an
ABI change if that struct were externally exposed, but it is not, so
it's safe to unilaterally remove it.
