arm64/syscall: Include asm/ptrace.h in syscall_wrapper header. (2022-11-09 09:52:25 +0000)

----------------------------------------------------------------
arm64 fixes:

- Another fix for rodata=full. Since rodata= is not a simple boolean on
arm64 (accepting 'full' as well), it got inadvertently broken by
changes in the core code. If rodata=on is the default and rodata=off
is passed on the kernel command line, rodata_full is never disabled.

- Fix gcc compiler warning of shifting 0xc0 into bits 31:24 without an
explicit conversion to u32 (triggered by the AMPERE1 MIDR definition).

- Include asm/ptrace.h in asm/syscall_wrapper.h to fix an incomplete
struct pt_regs type causing the BPF verifier to refuse to load a
tracing program which accesses pt_regs.
