This PR allows you to do things like /bin/sccache /usr/lib/sccache/gcc main.c

It can seem weird at first, but the same mechanism already existed for ccache. Personally, I had an issue with a build system that insisted on putting sccache as a wrapper, when I already had gcc as a sccache symlink, which is what prompted that PR

there's a change of behaviour for absolute path (they are now still changed to avoid wrappers) so I would understand if you didn't accept this PR

Make /bin/sccache /usr/lib/sccache/gcc main.c work

### [`v0.16.0`](https://github.com/mozilla/sccache/releases/tag/v0.16.0)

[Compare Source](mozilla/sccache@v0.15.0...v0.16.0)

##### sccache 0.16.0

##### Summary

sccache 0.16.0 is a smaller, stabilizing release on top of 0.15.0's multi-tier caching work, with a few new capabilities:

- **Read-only backends**: Any storage backend can now be marked read-only, not just a select few ([#&#8203;2705](mozilla/sccache#2705)).
- **Remote execution on aarch64**: Distributed/remote execution now works on Linux aarch64, including fixes for `ldd` output parsing and toolchain packaging on non-x86\_64 Linux ([#&#8203;2668](mozilla/sccache#2668)).
- **CUDA**: `nvcc`'s `--dependency-output` argument is now handled ([#&#8203;2708](mozilla/sccache#2708)).
- **Resilience**: Fall back to a direct cache write when tempfile creation on the same filesystem fails ([#&#8203;2369](mozilla/sccache#2369)), and give a meaningful error when a multi-level chain references a backend that wasn't compiled in ([#&#8203;2695](mozilla/sccache#2695)).
- **Client efficiency**: The client and dist-client now use a single-threaded tokio runtime, avoiding a thread explosion when many short-lived clients run on many-core hosts ([#&#8203;2704](mozilla/sccache#2704)).
- **Correctness**: Strip `SCCACHE_BASEDIRS` from escaped-backslash paths on Windows ([#&#8203;2736](mozilla/sccache#2736)), ignore empty-set environment values in config ([#&#8203;2639](mozilla/sccache#2639)), and avoid the sccache wrapper when resolving the real compiler ([#&#8203;2720](mozilla/sccache#2720)).
- **Security/logging**: JWT keys and cert digests are now base64-encoded in logs ([#&#8203;2712](mozilla/sccache#2712)), plus general logging improvements ([#&#8203;2734](mozilla/sccache#2734)).
