[committed, testsuite] Fix pathname prefix and timeout issues in gdb.mi/mi-pending.exp

[Sandra Loosemore <sandra at codesourcery dot com>]

This patch fixes another problem with hard-wired pathname prefixes that 
are inappropriate for remote-host testing.  This time it's in the 
command used to set the pending breakpoint in gdb.mi/mi-pending.exp.  It 
was setting the breakpoint using the pathname to the source file on the 
host where the .exp file is running, which may not be correct on the 
remote host.  The net result is that it was failing ever to set or stop 
at the breakpoint in its intended location.  Using the bare basename of 
the file, without a directory prefix, seems to work fine for both the 
local and remote testing scenarios.

Also, for some reason the continue-to-breakpoint test had a hard-wired 
timeout of 5 seconds.  This was tripping for the slow-ish remote target 
I've been testing on, and I don't see any purpose in overriding the 
target board's default timeout, so I've removed that.

I think both of these fixes qualify as obvious, so I've committed this 
patch.

	gdb/testsuite/
	* gdb.mi/mi-pending.exp: Don't use directory prefix when setting
	the pending breakpoint.  Remove timeout override for "Run till
	MI pending breakpoint on pendfunc3 on thread 2" test.
