Nowadays, GnuPG 2.1 or later has --pinentry-mode option, which provides
a way to bypass the graphical pinentry prompt, like:

$ gpg --batch --decrypt --pinetry-mode=loopback authinfo.gpg

which just behaves like gpg1.  I added the support to epg.el (see
epg-pinentry-mode) some time ago, but not yet added any user option in
epa.el.

Patches (and testing) are welcome.
