webapp.eclass: optimize webapp_serverowned() and inline webapp_strip_*()

Some ebuilds invoke webapp_serverowned() with -R, causing the eclass to
iterate over a large set of files. Within the iteration's body the
eclass forks multiple times to invoke the webapp_strip, which is very
inefficient and causes a huge slowdown.

This optimizes webapp_serverowned() by replacing the iteration and call
to the "strip" functions with a single equivalent invocation of find
to iterates all the files.

Furthermore, all remaining invocations of webapp_strip_*() are inlined.
