zathura hangs after invoking `print` #431

Noticed today that :print started to hang zathura entirely. No print dialog is shown, no CPU is used, zathura can only be killed. After some debugging it turns out to be a problem with default sandbox that explicitly disallows vmsplice.

In my particular setup I'm connecting to network CUPS printer over secure connection using GnuTLS configured to make use of AF_ALG kernel crypto API through libkcapi which in turn makes use of vmsplice: https://github.com/smuellerDD/libkcapi/blob/0e3e2032a97c51697a5134ca6eabbd5708e9498a/lib/kcapi-kernel-if.c#L324
