LLDB needs to sometimes run utility expressions such as loading libraries via a
call to `dlopen`. These utility expressions have a timeout associated with them
which is only 15 seconds (and 60 on sanitized builds).
I suspect our expressions reaching this timeout is the reason why
TestLoadUsingPaths.py sometimes fails to load libraries and produces this error:
```
File "../TestLoadUsingPaths.py", line 78, in test_load_using_paths
self.assertNotEqual(token, lldb.LLDB_INVALID_IMAGE_TOKEN, "Got a valid
token")
```
This patch bumps the timeout to 10 minutes. There is no good reason why this
timeout should exist in the first place on test bots, and maybe we should
remove them or make them fatal errors on the test bots. But for now this patch
should at least fix the test randomly failing on very slow bots.
