[PATCH] ci: only warn about perforce/git-lfs/JGit on platforms that need them

["Harald Nordgren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Harald Nordgren <haraldnordgren@gmail.com>

perforce, git-lfs, and JGit test git's own interop code, not anything
platform-specific, so installing them once on ubuntu-* (all three)
and macos-* (perforce) is enough coverage. debian, i386/ubuntu,
alpine, fedora and almalinux never install them, yet the presence
check at the end of the script warned on all of them anyway.

Scope each check to the platforms that attempt the install, so a
warning means one actually failed.

    ci: only warn about perforce/git-lfs/JGit on platforms that need them
    
    Only warn about a missing perforce/git-lfs/JGit install on the platforms
    that actually need and attempt them (ubuntu-*, plus macOS for perforce),
    since every other platform never installs them and was warning
    regardless.
