Disable bracketed paste mode in GDB tests
I have a patch to import GNU readline 8.1 into GDB. However, when
running the tests, there were a number of failures due to "bracketed
paste mode". This is a terminal feature that readline 8.1 enables by
default.
The simplest way to work around this was to always make a ".inputrc"
for GDB tests that will tell readline to disable brackted paste mode.
