package/musl: fix conflict with riscv kernel headers

Browse source 
Add two upstream patches fixing musl vs kernel headers conflict. This
fixes build of strace for risc64 at it happens to use headers from both
sources.

Modify patch #3 to leave a single newline in user.h. Otherwise 'patch
-E' in apply-patches.sh deletes user.h instead of leaving it empty.

Fixes (strace):

Subject: [PATCH] fix risc64 conflict with kernel headers
Rename user registers struct definitions to avoid conflict with the
asm/ptrace.h kernel header that defines the same structs. Use the
__riscv_mc prefix as glibc does.

Subject: [PATCH] remove riscv64 bits/user.h contents
the contents conflicted with asm/ptrace.h. glibc does not provide
anything in user.h for riscv, so software cannot be depending on it.
simplified from patch submitted by Baruch Siach.
[ baruch: add empty line so that 'patch -E' doesn't delete user.h ]
