[RFA/testsuite] Reduce the default test timeout to 30 seconds for Unix.

[Joel Brobecker <brobecker@adacore.com>]

Hello,

This is something that I noticed while working on testcase timeouts...

This patch reduces the timeout duration used for all "unix" native
configurations from 60 seconds down to 30 seconds.  Even under NFS
and heavy loads, 60 seconds seems a bit excessive.

This might not be very important if we manage to find a way to implement
the idea of aborting a testcase as soon as the first timeout gets hit.
But in the menatime, this reduces significantly the amount of time spend
multi-timing out... (no idea on how to do that so far, though)

In the few situations where 30 seconds, which is already 3 times the
dejagnu default, is not enough, the user has the possibility of changing
the timeout duration back to any value by definining gdb_test_timeout.

gdb/testsuite/ChangeLog:

        * config/unix.exp (timeout): Change value to 30.

Tested on x86_64-linux.  No regression.

Any objection?
Thanks,
