Bug 1871064 [wpt PR 43752] - Retry firefox_android package install, a=testonly

Automatic update from web-platform-tests
Retry firefox_android package install

Instead of having a single very long timeout, retry the install from
the start up to 5 times.

It appears that when the install fails it's not running into a
timeout, but for some reason the emulator is in the wrong state. In
this case restarting the operation from scratch works. Locally three
attempts in total were sometimes required, but this allows up to 5
retries (six total attempts) since CI machines may be slower.
