dumpstate: Properly handle unfound pid

The function GetPidByName() returns -1 if we can't find the
pid.  But since we had 'pid' as unsigned, this became a huge
positive number for us, and we didn't fail the "pid > 0" check
as expected.

We switch 'pid' to a signed int, so now this logic flows as
expected.

Test: Grab a bugreport on a device without /system/bin/anrd and confirm we no longer get the "Failed to find" error in logcat.
