Avoid pagination in attach-32.exp

When running test-case attach-32.exp from
gdb-6.3-inferior-notification-20050721.patch, we run into:

The test-case hangs because pagination is activated, with height == 25
due to gdb_init.

Fix this by starting gdb using -iex "set width 0" -iex "set height 0" -quiet,
similar to how it is done in attach.exp (see commit fef1b2933d "Avoid
pagination in attach.exp").

Tested on x86_64-linux.

	* gdb.base/attach-32.exp: Start gdb using -iex "set width 0" -iex
	"set height 0" -quiet.
