2021-07-04cpio: Fix device number calculation.Tobias Geerinckx-Rice
“dev_t in glibc is a 64-bit quantity, with 32-bit major and minor numbers.” — glibc's <bits/sysmacros.h> The "tests/cpio.scm" was failing because (guix cpio) treated it as a 16-bit quantity instead, leading to header mismatches with the GNU cpio reference output. * guix/cpio.scm (device-number, device->major+minor): Use all the bits.
