[PATCH] [testsuite] Raise timeout for gdb.threads/process-dies-while-detaching.exp

[Luis Machado]

This test spawns a lot of threads, and I see intermitent failures on
aarch64-linux running Ubuntu 18.04/20.04.

Raise the timeout to give the test some additional time to fetch all the
output being printed and wait for GDB to do its thing.

gdb/testsuite/ChangeLog:

YYYY-MM-DD  Luis Machado  <luis.machado@linaro.org>

	* gdb.threads/process-dies-while-detaching.exp (do_test): Raise
	timeout factor to 4.
