tests: Add tests for ScreenRecoveryUI.
In order to support that, this CL adds Paths::set_resource_dir() to
override the default resource dir ("/res/images/") that's only available
under recovery. Note that since there're external modules depending on
libminui, it adds a separate function of res_set_resource_dir(), instead
of requiring the dependency on libotautil for everyone.
Test: mmma -j bootable/recovery
Test: Run recovery_unit_test on marlin.
