Added redundant mkdir -pv "${COOKBOOK_STAGE}/usr/bin" before cp
in the base recipe's BINS install loop. The initial mkdir at line 159
creates the staging directory, but during multi-package builds the
staging area may be cleaned or the build directory context may shift.
This fixes the 'cp: cannot create regular file .../stage.tmp/usr/bin:
No such file or directory' error during base package build.
