insane: use oe.cachedpath.CachedPath instead of os.path

The insane QAPATHTESTs make many os.stat() calls, the majority of which
are redundant with caching as the initial sweep does a stat() on every
entry to determine if it is a file or a directory, and from then on each
test that does further stat()s is redundant as the tree doesn't change.

Switch os.stat() and friends (os.path.isfile(), etc) to use a common
oe.cachedpath.CachedPath() instance that is shared between all of the
functions, meaning only one stat is done.

In my test case of ltp:do_package_qa, this reduces the time taken from
44s to 37s.
