Subject: [PATCH] file_sys: apply case-insensitive search to mods_path on
 GNU/Linux and macOS (#4312)

The case-insensitive fallback search() in GetHostPath is only
invoked for patch_path and host_path, so mods whose file or folder
capitalization does not exactly match the guest path are silently
bypassed even when the files are present. Mirror the existing
search(patch_path) pass for mods_path, placed first to preserve
mod > patch > base precedence.
