The problem is that some distributions rename "gpg2" to "gpg" and it's
not that simple to detect it's v1.  Maybe a better solution would be to
define `epg-config--program-alist' as a normal defvar rather than
defconst, bind it in `with-epg-tests', and find the correct gpg v1
executable.  I'll try to write a patch later today.
