(#12357) Fix broken compatibility with Puppet 2.6
Without this patch, the previous change set to the validate_absolute_path() parser function contains Puppet 2.6 incompatible changes. stdlib 2.x is compatible with Puppet 2.6. These changes are a problem because we cannot introduce backwards incompatible changes in a minor release. This patch fixes the problem by back porting the implementation of the `Puppet::Util.absolute_path?` from 2.7.x to the function block itself. The function block tests to see if `Puppet::Util.absolute_path?` will respond and if not, falls back to the inline back ported implementation. The spec tests have been updated to simulate the behavior of Puppet 2.6 even when running with Puppet 2.7.
