security/stunnel: Improve port
- Remove GNU_CONFIGURE_MANPREFIX (redundant)
- Remove if statement for libressl, already covered by BROKEN_SSL definition
- Rework multiple REINPLACE_CMD commands, remove no longer valid ones and remove requirement of -E switch. These should also be a bit easier to follow
- Use modern framework helpers for options
- Remove redundant LDFLAGS
- Rework Makefile layout to more closely follow Porters Handbook and reduces Makefile size overall
- Don't install stunnel.logrotate and stunnel.rh.init (cleans up pkg-plist)
- Remove bash-completion from pkg-plist, not installed unless specified during configure stage
