run-command: add pre-exec callback
This is a function provided by the caller which is called
_after_ the process is forked, but before the spawned
program is executed. On platforms (like mingw) where
subprocesses are forked and executed in a single call, the
preexec callback is simply ignored.
This will be used in the following patch to do some setup
for 'less' that must happen in the forked child.
