unneeded SIG prefix in $Config{sig_name}

[mstetson]

The module documentation says that signal names in the Config module's sig_name list do not have a SIG prefix, but cnf/configure_sigs.sh puts one in. This prevents, for example, installing SmokePing using a version of Perl built with perl-cross. Here's a fix:

Applied, thanks.
