[GDBRemoteCommunicationClient] Increase timeout for qfProcessInfo packet.

Summary:
The test in TestPlatformCommand which runs "platform process list" has
been timing out for Android when running running dosep.py with
LLDB_TEST_THREADS=8. This patch increases the packet timeout to a large
value of 1min to accommodate the long time required for a response for
the qfProcessInfo packet on Android.

Test Plan: LLDB_TEST_THREADS=8 ./dosep.py on Android.
