[Pam-developers] pam_access: First check for the (group) syntax

[Tomas Mraz]

Hi,

reportedly there are sites where group names contain @ character. This
patch for pam_access tests for the group match via the (group) syntax
before proceeding with other matches (namely the user@host pattern).
This allows matching groups with the @ character.

OK to commit?
