Add 'if-host-match' option to m_sslinfo oper autologin configuration.•••This adds an option to perform the source host check (which is usually
performed on manual oper login) in addition to the certificate fingerprint
check when automatically logging in opers upon connection to the ircd.
Use /run/inspircd as the runtime directory on Linux.•••Unfortunately some tooling like AppArmor is not smart enough to
follow the symlink from /var/run to /run so we need to explicitly
set the path. This fixes running InspIRCd without --nopid on some
systems.
