Resolve the tracked locations in profile saver

The profile saver takes the dex locations it has to track as they are.
On the buildbot the locations are symlinked, but the dex file may be
compiled with an absolute path. This may cause a mismatch and cause the
dex file to not be profiled (test 595-profile-saving will fail).

Note that this is a valid use case in production as well. It may happen
for secondary dex files which can be loaded via symlinks.

Test: test/run-test --output-path /tmp/link --always-clean --host --prebuild --interpreter --no-relocate --runtime-option -Xcheck:jni --no-image --64 595-profile-saving
       test/run-test  --output-path /tmp/link --always-clean --host
--no-prebuild --jit --no-relocate --runtime-option -Xcheck:jni
--runtime-option -verbose:profiler --64  595-profile-saving
