host/lib/subprocess: replace constructor function & perror with VB2_DEBUG
Currently this had perror to print the error message, but we can get
rid of this and the constructor function reasonably if we switch to
VB2_DEBUG.
This was changed since the Loonix team cannot rely on glibc-specific
behaviors, and passing argv to constructor functions is
glibc-specific. See the notes on cl/316913250 for a little bit of
background.
