[PATCH v2] backends/ppc_initreg.c: include <asm/ptrace.h>.

["Érico Nogueira" <ericonr@disroot.org>]

From: Érico Rolim <erico.erc@gmail.com>

Necessary on musl for struct pt_regs definition, doesn't affect the
build on glibc.

Signed-off-by: Érico Rolim <erico.erc@gmail.com>

Sending a v2 with the main difference being a slightly different commit
message and signed-off-by line.

I'm a bit hesitant on this being the correct patch, so I'd ask that you
only merge if you think it makes total sense, otherwise I'd like to sit
on it for a bit. For the record, it has been in use in Void Linux since
the end of 2019.
