record_android_trace: fix -a* and uprev tracebox.

This CL makes the tools/record_android_trace compatible
with older (pre-P) versions of Android.
- Fix the escaping of -a*. Even when passing it correctly
  on the host (e.g. -a '*') the * would still be escaped
  by the shell on the device (the quotes are stripped by the
  host bash and we don't see them in the script).
- Improve examples in --help.
- Uprev tracebox to pick-up aosp/1714352.

Test: manual:
tools/record_android_trace -b 256mb -t 60s sched gfx view irq adb camera -a* --sideload
