The results from these functions have boolean semantics. They're
returning `int` prior to this CL, with some of them mixing 0 and
InstallResult. Note that SetUpNonAbUpdateCommands() was returning
INSTALL_CORRUPT / INSTALL_ERROR / 0 prior to this change, but all the
callers handle INSTALL_CORRUPT and INSTALL_ERROR the same way.
This CL changes them to return bool instead.
Test: `mmma -j bootable/recovery`
Test: TreeHugger
Test: Sideload on taimen.

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`
