[ptxdist] [PATCH v3 1/2] php: reanimate PHP as PHP8

[Andreas Helmcke <ahelmcke@ela-soft.com>]

PHP5 is gone with commit
 f356f581e17a9474bdc01dbe3907f96558101609   "php5: remove old package"

Let's try now with PHP8 instead and a minimal feature set due to limited
test options. The remaining features can be extended on demand.
