Move /sbin/charger to /system/bin/charger.

With the CLs in the same topic, it's being built as a dynamically linked
executable. And this applies to normal boot (including charger mode) and
recovery mode both.

/system/bin/charger under normal boot will be labeled as charger_exec,
which has the attribute of system_file_type.

The file in recovery image will still be labeled as rootfs. So we keep
the domain_trans rule for rootfs file, but allowing for recovery mode
only.

Bug: 73660730
Test: Boot into charger mode on taimen. Check that charger UI works.
Test: Boot into recovery mode. Check that charger process works.
