ui: allow capture of subprocess output

We want to capture hooks output during bundle2 processing. For this purpose we
introduce a new 'subproc' argument to 'ui.pushbuffer'. When set, the output of
sub process created through 'ui.system' will be captured in the buffer too.

This will be used in the next changeset.
