Mk/bsd.sites.mk: Fix fetch with GL_TUPLE site:account:project:commit:group style entries
Something like
GL_TUPLE= https://gitlab.redox-os.org:redox-os:calc:afba9c5d184ddb9db5e4e71dc357da0499e212cf:calculate
fails to fetch because GL_SITE_calculate still has the colon left after parsing:

$ make -V GL_SITE_calculate

Changing the already complex regular expressions to correct this
would make them even more complex. Instead we correct the :: that
appears in GL_SITE after parsing GL_TUPLE.
