sysutils/google-compute-engine-oslogin: Update to 1.5.2

• Pass maintainership to submitter
• Remove all patches because they're merged by upstream

While I'm here:

• Pet portlint
• Strip info from another shared library to level up port compliance

Changelog since 1.4.3:

• Fix alternate challenge section for two factor authentication.
• Fix FreeBSD compatibility issues in the control file.
• Use pam_group to provide users with default groups.
• Add compat.h to support FreeBSD.
• Exit immediately after a two factor authentication failure.
• Add support for Google phone prompt challenges.
