lesstest logging: follow Automake simple test format

[justeph]

Hi,
I would like to know if there is a particular reason for the logging format of the lesstest? I was wondering if we can change it to follow the Automake simple test format? For example instead of:

TEST version.c.lt
OK   version.c (38 steps)

we could have:

PASS: version.c

This would be helpful for Yocto integration, because Yocto uses ptest for running tests and it uses the Automake simple test format to unify tests output.
As a work around in the Yocto integration we can still write a wrapper script to get the appropriate format, but having it merged here would be easier and can be beneficial for other project as well.

What do you think? I can do a PR if this is something you would accept.
Best
Julien
