tests: Merge recovery_component_test into recovery_unit_test.

Most of the tests in component/ are in fact unit tests. And it doesn't
look practically beneficial to distinguish between the two:
- They have the same test setup;
- We always run both (recovery_unit_test and recovery_component_test)
  at the same time;
- Breaking any of them would be equally bad.

This CL merges the tests in recovery_component_test into
recovery_unit_test to save the effort to maintain both.

Test: Run recovery_unit_test on marlin (via `adb sync data`).
Test: `atest recovery_unit_test`
