On two separate occasions GitHub added random garbage into the hosts
file breaking our tests. This change adds a permanent workaround for
this kind of stuff. It will remove everything that doesn't look like
a correct syntax from the file.
The regex is not perfect, but it should be sufficient for most cases.
It allows empty lines, comments and a valid 'IP NAME[ NAME]...' lines,
where 'IP' resembles an IP address and the 'NAME' consists of valid
DNS characters. Under normal conditions the diff should always be
empty.
