[gdb/testsuite] Limit verbose scope in gdb.base/break-interp.exp

Browse Source 
I'm running into the following failure (and 17 more like it) in
gdb.base/break-interp.exp:
...

...

The problem is that the test uses verbose mode to detect the "PIE (Position
Independent Executable) displacement" messages, but the verbose mode also
triggers "Reading in symbols for" messages, which may appear in the middle of
a backtrace (or not, depending on whether debug info is available).

[ In fact, the messages appear in the middle of a backtrace line, which is
PR25613. ]

Fix these FAILs by limiting the scope of verbose to the parts of the test that
need it.

Tested on x86_64-linux.
