Fixes to README of sysutils/anacron

[Andreas Kusalananda Kähäri]

Hi,

I was once the port maintainer of sysutils/anacron. I wrote the
pkg/README file and it's been bothering me ever since.

I have attached a patch that fixes it in such a way that

* Environtment variables are the same as in the default crontab for
  root.

* Absolute paths for /bin/sh are being used.

* No pipe to tee (why did I even have that?).

* Suggest adding an @hourly job to run anacron in root's crontab.

* Fixes @hourly and @reboot crontab suggestions so that it tests if the
  executable is present.  Is this a good idea? Maybe it's better to let
  it fail, so that it's spotted?

Also:

* Bump revision in Makefile.


With kind regards,
Kusalananda
