[05/21] environment: make `get_graft_file()` accept a repository

Commit Message

Patrick Steinhardt Aug. 29, 2024, 9:38 a.m. UTC

The `get_graft_file()` function retrieves the path to the graft file of
`the_repository`. Make it accept a `struct repository` such that it can
work on arbitrary repositories and make it part of the repository
subsystem. This reduces our reliance on `the_repository` and clarifies
scope.
