fix(ubuntu): add commands so apt-get can install libc

specifically:

rm /var/lib/dpkg/info/libc-bin.* && apt-get clean

to fix errors like

spinnaker#10 97.63 Processing triggers for libc-bin (2.35-0ubuntu3.8) ...
spinnaker#10 97.71 qemu: uncaught target signal 11 (Segmentation fault) - core dumped
spinnaker#10 98.12 Segmentation fault (core dumped)
spinnaker#10 98.17 qemu: uncaught target signal 11 (Segmentation fault) - core dumped
spinnaker#10 98.55 Segmentation fault (core dumped)
spinnaker#10 98.56 dpkg: error processing package libc-bin (--configure):
spinnaker#10 98.56  installed libc-bin package post-installation script subprocess returned error exit status 139
