servo: Merge #15609 - Android cleanup (from fabricedesre:android-cleanup); r=Wafflespeanut

<!-- Please describe your changes on the following line: -->
As I dive in the Android code, a bit of cleanup:
- jni/main.c was totally useless, and its presence misleading. I left the jni/ directory to please `ndk-build`.
- the logging redirection in servo/main.rs was redondant with the implementation in the injected android glue.

Most other changes are just due to my editor doing a `rustfmt` when saving files.
I also turned on RUST_LOG to `debug` by default, that helps quite a bit to see what's happening.

---
<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X ] `./mach build -d` does not report any errors
- [X ] `./mach test-tidy` does not report any errors
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [ ] There are tests for these changes OR
- [X ] These changes do not require tests because unfortunately we don't have Android tests.

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
