chat/ircd-hybrid: Updates to 8.2.30

Changes since 8.2.29:

-- Noteworthy changes in version 8.2.30 (2020-03-01)
o) "QUOTE HELP extban" didn't work because the extban help file hasn't been
  installed properly during 'make install'
o) Fixed broken libcrypto detection which caused the ircd not to work with
  openssl under certain circumstances
o) Extban $n of type 'acting' has been implemented. This extban prevents
  matching users from changing their nick while in the channel. Users
  with voice or above are not affected.
o) Channel mode +N has been changed so channel members with +v can change
  their nick name as well
o) For a full list of all changes in this release, see https://git.io/JvgAq
