Support itk with mod php

[corvus-ch]

We have the company policy to use itk on all our production php installations. The restriction to mpm prefork renders the Puppetlabs apache module unusable for our cause.

I extended the integrity checks in mod::php so it also can be used with itk.

looks good, I'd like to see travis actually pass, which now that master is fixed it should

[corvus-ch]

Is there some action required to retrigger Travis or will that happen anyway?

[hunner]

If you do git rebase master && git push --force it should re-trigger travis.

[hunner]

Err, that won't work since you sent from your master branch. Fetch the puppetlabs remote and rebase your local branch onto that.

@corvus-ch Can you update spec/classes/mod/php_spec.rb with a case with itk enabled instead of prefork?

[corvus-ch]

Sure, I can. I do not know systems other than the Debian. So the test for FreeBSD and RedHat is best guess from what was there.

@corvus-ch those tests look good, but could you rebase and squash down to a single commit? Thanks!

[underscorgan]

@corvus-ch thanks for the contribution!

@mhaskel Thanks for accepting it. I am glad that I could be of help.
