cros_flash: Fix the issue with /test xbuddy path

Currently there is some weirdness in the implementation of xbuddy path
translations and unfortunately the xbuddy links like
remote/reef/latest/test is broken. This CL simplifies the path
translation a bit better.

Also deprecates TranslatedPathToLocalPath.

BUG=b:172083615
TEST=both inside and outside chroot:
cros flash --debug --no-ping --no-wipe --no-reboot [$dut] xbuddy://remote/reef/latest-dev
cros flash --debug --no-ping --no-wipe --no-reboot [$dut] xbuddy://remote/reef/latest-dev/test
cros flash --debug --no-ping --no-wipe --no-reboot [$dut] xbuddy://local/reef/latest/
cros analyze-image --debug --board=reef --version=R88-13575.0.0

TEST=inside chromium checkout
~/chromium/src/third_party/chromite $ ./bin/cros flash --debug --no-ping --no-wipe --no-reboot [$dut] xbuddy://remote/latest
