[RFC PATCH 1/2] sh-setup: Make die take the error code as param.

die used to print all parameters and then exit with code 1. Now die
prints the first parameter and uses the optional second parameter as the
exit code. The default exit code is 1.

This allows scripts to control the exit code when they call die.

All current git-code only uses the first parameter of die today so this
change has no impact on them.
