BPF program signing support is gated by the kernel configuration option `CONFIG_SYSTEM_DATA_VERIFICATION`. This kconfig is hidden, only enabled when other kconfigs that depend on it are enabled. Enabling `CONFIG_FS_VERITY` and `CONFIG_FS_VERITY_BUILTIN_SIGNATURES` seemed to be the best way to enable support without to much side effects.

This commit enables RSA, ECDSA, and MLDSA signing algorithms as well as SHA256, SHA512, and SHA3 hashing algorithms in the kernel configuration. Enabling these in the kernel to allow verification of different signature types for BPF programs. Signed-off-by: Dylan Reimerink <dylan.reimerink@isovalent.com>
