tools headers UAPI s390: Sync ptrace.h kernel headers

To pick up the changes from:

56e62a7370283601 ("s390: convert to generic entry")

That only adds two new defines, so shouldn't cause problems when
building the BPF selftests.

Silencing this perf build warning:

Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/ptrace.h' differs from latest version at 'arch/s390/include/uapi/asm/ptrace.h'
