apexd: remove two most spammy log lines

"Found bundled key in package" is the biggest contributor, while not
providing a lot of value for debugging (we are expecting all the APEXes
to have bundled key anyway).

"Skipped when bootstrapping" doesn't provide a lot of information as
well. We are more interested in the APEXes that weren't skipped during
bootstrap, and we already log them.

Test: adb reboot, checked logcat
