checkhealth: do not use exepath with host_prog (#8784)

Browse Source 
This would need to get `expand`ed to not become empty, and is being
handled by s:check_bin already.

`s:check_bin` will also complain about e.g.
"~/.pyenv/versions/3.6.6/bin/python" not being executable, but that
reflects that the host will fail to start with it.

Fixes #8778
