sysutils/ipfs-go: fix rc script

• Fix the rc script when default ipfs_go_path is used
• Fix the logging by switching to uses the syslog logging in daemon
• Switch the init to using the --init flag to the ipfs daemon command
• Fixes the version string since the tarball provided by upstream doesn't match the tag for this release (has version string wrong)
• Allow overriding IPFS_USER/GROUP/HOME at build time
• Remove unnecessary BEFORE: LOGIN from rc script
