patches: fix crypto module packaging for older kernels (0060)

Browse Source 
The MediaTek SDK uses kernel 5.4.271 which requires adjustments to
the crypto module packaging:

1. The gf128mul module location changed between kernel versions:
   - Kernels < 6.2: crypto/gf128mul.ko
   - Kernels >= 6.2: lib/crypto/gf128mul.ko
   Add version-specific file paths to handle both locations.

2. The sha512-arm64 module doesn't exist in older ARM64 kernels like 5.4,
   causing package build failures. Exclude this module for the mt7981
   target which uses the older MediaTek SDK kernel.

These changes allow the kernel modules to build correctly whilst
maintaining compatibility with newer kernel versions.
