profiles: seccomp: update to Linux 5.11 syscall list

These syscalls (some of which have been in Linux for a while but were
missing from the profile) fall into a few buckets:

 * close_range(2), epoll_wait2(2) are just extensions of existing "safe
   for everyone" syscalls.

 * The mountv2 API syscalls (fs*(2), move_mount(2), open_tree(2)) are
   all equivalent to aspects of mount(2) and thus go into the
   CAP_SYS_ADMIN category.

 * process_madvise(2) is similar to the other process_*(2) syscalls and
   thus goes in the CAP_SYS_PTRACE category.
