kernel: use upstream patches for musl

This replaces the current patches used to make the kernel headers
compatible with musl with the version which was accepted upstream. This
is included in upstream kernel 4.15.
This was compile tested with iproute2 build on all supported kernel
versions with musl and one one with glibc.

-From: David Heidelberger <david.heidelberger@ixit.cz>
-Subject: uapi/libc-compat.h: do not rely on __GLIBC__
-
-Musl provides the same structs as glibc, but does not provide a define to
-allow its detection. Since the absence of __GLIBC__ also can mean that it
-is included from the kernel, change the __GLIBC__ detection to
-!__KERNEL__, which should always be true when included from userspace.
