Fix app fetcher php comparison to allow wider ranges 

When app app specifies php 7.4 as upper limit we have to allow the
installation on php>7.4.0. The previous version check didn't do that.
This adjusts the regexes to discard any irrelevant suffix after the
three version numbers so that we can use more fine granular checks than
php's version_compare can do out of the box, like for php 7.4 we only
compare the major and minor version numbers and ignore the patch level.
