Increase the number of long times by extension to report from 5 to 10
since java build steps produce a number of different extension types. It
is difficult to distinguish between android vs non-android builds, so
increase this default for all platforms.

Prioritize .jar outputs for java targets and allow up to two levels of
extensions to be recognized.

e.g.
file.interface.jar would have .interface.jar as its full extension.
file.javac.jar would have .javac.jar as its full extension.

Some of these build steps require .jar outputs, which is why these
targets use a secondary extension to differentiate.
