[PATCH RFA] gdb.base/signals.exp: explicitly set count = 0

[Orjan Friberg <orjan dot friberg at axis dot com>]

gdb.base/signals.exp runs the main function in signals.c twice. 
signal.c contains a static variable count which is initialized to 0. 
The second time the main function is run, the test case relies on count
being 0, which depends on how runto_main is implemented for the target. 
My target does a simple "jump *main", which obviously doesn't
re-initialize count to 0.  This patch sets count to 0 explicitly.

Ok to commit?
