[gdb/testsuite] Make inferior_exited_re match a single line

The current inferior_exited_re regexp contains a '.*':
...
set inferior_exited_re "(?:\\\[Inferior \[0-9\]+ \\(.*\\) exited)"
...

This means that while matching a single line:
...
$ tclsh
% set re "(?:\\\[Inferior \[0-9\]+ \\(.*\\) exited)"
(?:\[Inferior [0-9]+ \(.*\) exited)
% set line "\[Inferior 1 (process 33) exited\]\n"
[Inferior 1 (process 33) exited]

% regexp $re $line
1
...
it also matches more than one line:
...
$ tclsh
% set re "(?:\\\[Inferior \[0-9\]+ \\(.*\\) exited)"
(?:\[Inferior [0-9]+ \(.*\) exited)
% set line "\[Inferior 1 (process 33) exited\]\n\[Inferior 2 (process 44) exited\]\n"
[Inferior 1 (process 33) exited]
[Inferior 2 (process 44) exited]

% regexp $re $line
1
...

Fix this by using "\[^\n\r\]*" instead of ".*".

Build and reg-tested on x86_64-linux.
