Subject: [PATCH] CI: Add workaround for github uppercase usernames

The workflow defined in tools.yml and kernel.yml used to fail on
forked repositories of contributers whose github username contains
uppercase letters.

A workaround mentioned in
https://github.com/orgs/community/discussions/27086 and
https://stackoverflow.com/questions/70326569/ is applied.

(cherry picked from commit c27b43956407f3adc3cc2693792acd6b40a01877)
