[PATCH 2/6] gdb, btrace: simplify gdb.btrace/multi-inferior.exp

[Markus Metzger <markus.t.metzger@intel.com>]

We don't really need three inferiors to test multi-inferior recording.
We don't really need to start recording on the second inferior first.
We don't really need to check info record before starting recording.
If we were recording, there would be output, causing a fail.

This just complicates the test when there is something to debug.
