libchromeos: Prevent closing known bad fd in Process class.
When using ProcessImpl::BindFd the parent_fd is set to -1. This causes
the process to call close(-1) which will silently fail. This patch
avoids calling close on the parent_fd when it is -1 so we don't issue
a known bad call to close. This makes it easier to debug problems when
running such program with strace.
BUG=None
TEST=Unittests still pass.
