Fix ScanDirectoryFilesRecursively

Fixes a regression since 5.5, where `ScanDirectoryFilesRecursively` no
longer does the "recursively" part due to `path` being `static`.

The issue was once already fixed in
https://github.com/raysan5/raylib/commit/5530a3ceb88962066affa5db8e13b00b64444b37
but recently made it back it in.
