mod_skinny: add easy access to set blocking/non-blocking mode for skinny socket on a per-profile basis

FS-5223 FS-6603 on platforms that have SO_REUSEPORT it also implies SO_REUSEADDR, On platforms that only have SO_REUSEADDR it seems to imply both in the absence of SO_REUSEPORT.

no one seems to be okay with actually installing perl modules because it might require the permissions to acutally do so, instead, let the users figure out how to install them themselves so they can figure out how to have permissions and where they acutally go by themselves with no direction from us
