tests/docker: fix mistakes in ubuntu package lists

librados-dev is not required by QEMU directly, only librbd-dev.

glusterfs-common is not directly needed by QEMU.

QEMU uses ncursesw only on non-Windows hosts.

The clang package is clang 10.

flex and bison are not required by QEMU.

Standardize on nmap ncat implementation to match Fedora/CentOS.

Remove vim since it is not a build pre-requisite and no other containers
include it.
