dev-perl/Crypt-OpenPGP: Bump to version 1.120.0

dev-perl/Crypt-OpenPGP: Bump to version 1.120.0

- EAPI6
- Fix LICENSE

Upstream:
- Remove hard dependency on Math::Pari
- Use Digest::SHA instead of Digest::SHA1
- Update GnuPG defaults
- Fix error propagation when generating RSA key
- Avoid truncating encrypted packet when data looks "falsey"
- Propagate errors when Ciphers fail construction
- Added NoVersion parameter to ::Armour to avoid version header

Todo:
- Upstream indicated to use Alt::Crypt::RSA, but this
  implementation clashes with Crypt::RSA using the same files
  and pulls in a lot of modules. Crypt::RSA retained because
  its still compatible.
- Apparent Soft-Deps on Crypt::Random and friends, omitted
  until a sane way to handle them is found.
