gdb/testsuite: bump duration for the whole test in do_self_tests
When running gdb.gdb/python-helper.exp, I get some timeouts:
continue
Continuing.
print 1
FAIL: gdb.gdb/python-helper.exp: hit breakpoint in outer gdb (timeout)
At this time, GDB is actually processing the stop and reading in some
CUs. selftest_setup does bump the timeout, but it's not for the whole
test.
Since debugging GDB with GDB is (unfortunately) a bit slow, bump the
timeout for the whole duration of the setup and body. On my optimized
build, the command takes just a bit more than the current timeout of 10
seconds. But it's much slower if running the test on an unoptimized
build, so I think it's necessary to bump the timeout for that in any
case.
