webcookies: fix isdomainmatch() (fixes livejournal.com login)
when cookie is domain=example.com, then we implicitely add
dot to the domain name, which made us reject the cookie as the
request domain "example.com" != ".example.com". fix by making
isdomainmatch() skip the implicit dot in pattern before string
comparsion.
