init.debug.rc: enable etm/etm2dram when SJTAG is unlocked

Browse source 
Enables the debug features required an unlocked SJTAG to the section
`on property:ro.vendor.sjtag_ap_is_unlocked=true`, so they can be
enabled when 1. PD is available on non-fused device on boot, or 2. PD is
available after betterbug acquires it from the corp service.
