Subject: include: Include <unistd.h> in pidfd-utils.h for syscall()
Git-repo: https://github.com/util-linux/util-linux.git
Git-commit: 10add327c608b11b3d70215048aade4d1797b1fd
Patch-mainline: yes
References: kernel 6.9

In Glibc, <sys/syscall.h> only contains SYS_* macros and the syscall()
function is in <unistd.h>.  So include it.
