pygoscelis: Disable CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS

Browse Source 
It looks as the SoC on the T14s (AMD Ryzen 7 PRO 4750U) doesn’t support
this feature, while grep’ing through my distfiles (i.e. source code of
my programms) indicated some software actually makes use of it.

For more details see e.g.:
- man 7 pkeys
- Documentation/core-api/protection-keys.rst (in the kernel sources)
