doc: minor improvements in BUILDING.md

1. necessarily reliably => necessarily reliable
2. projects root directory => project's root directory
3. remove `console` highlighting, as `test` alone is highlighted
4. fix broken link for Android NDK
5. highlight the directory location `/usr/local/ssl/fips-2.0`
6. update expected output to an example for `process.versions.openssl` as the
   version displayed is not mentioned in the document
