[Minios-devel] [UNIKRAFT/MUSL PATCH V2 12/28] Use uk/bits/syscall_nrs.h instead of musl internal bits/syscall.h

[Gaulthier Gain <gaulthier.gain@xxxxxxxxx>]

This patch updates Makefile.uk and include/sys/syscall.h in order to
avoid generating a clone of syscall_nrs.h which is defined within
Unikraft.
