linux-pam: 1.3.1 or reason to stay with 1.3.0?

[dtzWill]

Issue description

pam 1.3.1 released a while back (~11 months ago), see: https://github.com/linux-pam/linux-pam/releases/tag/v1.3.1

repology suggests it's generally adopted elsewhere: https://repology.org/metapackage/pam/information

For something fundamental like PAM it seems we'd want to not mess around with older versions unless there was a reason-- although a quick review of the changes doesn't reveal a pressing need to upgrade either, so.... maybe we just don't want to break all the things? :)

Anyway wanted to ask to make sure it wasn't lost in flurry of PR's or something-- is there a reason to not move to 1.3.1?

The musl patch stack will need adjusting of course but otherwise....? :)
