Fix daemon startup with new glibc versions (>=2.35)

When running on systems that ship with the most recent release of glibc (2.35), we noticed that virtiofsd would fail when running as a regular user. This was down to one of viriofsd's child processes being killed by seccomp for attempting an rseq. So, add rseq to allowed syscalls, and bump libc bindings to the version that introduces SYS_rseq.
