pass: unittest: Change install path and test file name

Change install path and test file name. Tizen 6.5 requires the install
and naming format as  '/usr/bin/hal/[module name]-haltests'.

[Detailed changes]
- /usr/bin/pass_haltests -> /usr/bin/hal/power-haltests
- /usr/bin/pass_gtest    -> /usr/bin/pass-unittests

And replace -ENODEV with -ENOTSUP because hal-api-power uses
the more correct error value of -ENOTSUP.
