procutil: allow callers of runbgcommand to assume the process starts

Experimentally starting the subprocess can take as much as 40ms, and
for some of our use cases that's frivolous: we know the binary will
start, and if it doesn't we'd only ever ignore it and continue
anyway. This lets those use cases be faster.

### Nearest subset relation
# Nearest subset of filter X is a filter Y so that:

# * X - Y is as small as possible.
# This create and ordering used for branchmap purpose.
