envsetup: Fix $PROMPT_COMMAND

Change I200902f135d0c5c620a8eb3ce9cefdba318cf9d3 broke the android
PROMPT_COMMAND on scenarios where the existing prompt already had
a hardstatus adjustment, since appending it to Android's just clobbered
Android's in favor of the original.

So instead of appending them, inject android's at the beggining of the
existing one (and create a default if none exists)

envsetup: Really fix PROMPT_COMMAND handling

 * Add ANDROID_NO_PROMPT_COMMAND to not change it at all.
 * Export ANDROID_PROMPT_PREFIX so it can be used elsewhere.
