[lldb-dev] skip some tests with "check-lldb"

When using lit as the driver (which is the case for check-lldb), the test
granularity is at file-level: lit invokes dotest.py for every test file. You
should be able to specify files to skip with lit's --filter. 

With regards to threading, lit will schedule one instance of dotest.py on every
thread, which processes one test file. Unless you passed specific options for
dotest.py, the latter will run the different tests within that one file on
different threads as well. (IIRC)
