fix vector types in aarch64 register file structures
the ABI type for the vector registers in fpregset_t, struct fpsimd_context, and struct user_fpsimd_struct is __uint128_t, which was presumably originally not used because it's a nonstandard type, but its existence is mandated by the aarch64 psABI. use of the wrong type here broke software using these structures, and encouraged incorrect fixes with casts rather than reinterpretation of representation.
