gpgme: updated to 1.10.0

Noteworthy changes in version 1.10.0:
 * Now returns more specific error codes for decryption to distinguish
   between bad passphrase, user canceled, and no secret key.
 * Now returns key origin information if available.
 * Added context flag "auto-key-retrieve" to selectively enable the
   corresponding gpg option.
 * Added flag is_de_vs to decryption and verify results.
 * py: Use SEEK_SET as default for data.seek.
 * cpp: Various new APIs.
 * Reduced spawn overhead on Linux again.  Added new configure option
   --disable-linux-getdents to disable this feature for very old
   Linux versions.
 * Improved the Python bindings build system.
 * Made the test suite less fragile.
