[RemoteUtil] Fix output from Windows SSH commands (#90)

Adds an ArchType argument to many RemoteUtil methods, which is used to
replace -tt (forced pseudo-TTY allocation) by -T (no pseudo-TTY
allocation). The -tt option adds tons of ANSI escape sequences to the
output and makes it unparsable, even after removing the sequences, as
some sequences like "delete the last X characters" are not honoured.

An exception is BuildProcessStartInfoForSshPortForward, where
replacing -tt by -T would make the port forwarding process exit
immediately.
