Update 'lldb-remote-linux-ubuntu' builder, remove --min/max-gdbserver-port arguments. (llvm#244)

Removed `--min/max-gdbserver-port` arguments when executing the
lldb-server instance on the remote target host. Looks like these
arguments are not working properly, lets just avoid using them for
awhile.

Removed '--log-channel' and '--log-file' arguments for the lldb-server
instance as useless for this run configuration.

Removed the remote target rebooting after the tests get done.
