check_smtp: Strip angle brackets from -f argument, if provided

Apparently some people used -f '<nagios at example.com>' to work around
the bug I just fixed in the MAIL FROM: command generation.  Although
the resulting command wasn't RFC-compliant, it was working with some
MTAs, so let's continue to support this syntax now that we generate
RFC-compliant commands.
