[gdb/testsuite] Stabilize test name in gdb.base/style.exp

With test-case gdb.base/style.exp, I get:
...
PASS: gdb.base/style.exp: set width 88
...

The 88 is not a constant, it's a variable:
...
gdb_test_no_output "set width $desired_width"
...
which is calculated by parsing the output of "info files".

When running with target board unix/-m32, I get instead:
...
PASS: gdb.base/style.exp: set width 67
...

Stabilize the test name by using instead:
...
PASS: gdb.base/style.exp: set width to desired width
...

Tested on x86_64-linux.
