Syscall arguments are passed via an array of 64-bit values in struct
seccomp_data, but we were only inspecting the bottom 32 bits and not
even those correctly for BE systems.
Fortunately, the only case argument inspection was used was in the
socketcall filtering so using this for sandbox escape seems
impossible.

When updating hostkeys, accept RSA keys if
HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA
keys when any of the ssh-rsa-sha2-* methods was enabled in HostkeyAlgorithms
nit ssh-rsa (SHA1 signatures) was not. bz#2650 reported by Luis Ressel; ok
