Scrub TelephonyRegistry of package names on user builds

For privacy-constrained bug report types (e.g. connectivity), we should
be omitting package names on user builds, but UIDs are acceptable to
display, so we add those in a few more places. For full bug reports on
user builds, the UID can always be mapped back to a package name.

Test: inspect dumpsys telephony.registry on user build
