[committed][gdb/testsuite] Simplify gdb.base/info-types.exp.tcl

[Tom de Vries <tdevries@suse.de>]

Hi,

The regexp matching state machine in gdb.base/info-types.exp.tcl handles
"File .*:" lines individually.  Now that we do line-by-line matching, that's
no longer necessary.

Simplify accordingly.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
