[PATCH] base-files: Avoid problems if DISTRO_VERSION contains undefined variable

[PATCH] base-files: Avoid problems if DISTRO_VERSION contains undefined variable

[Peter Kjellerstedt]

If DISTRO_VERSION is defined to some undefined variable, e.g.,
DISTRO_VERSION = "${FOO_VERSION}", and /bin/sh is dash, then
do_install() would fail with an error such as:

  run.do_install.2945:193: run.do_install.2945: Syntax error:
  Unterminated quoted string

This was due to unexpanded Python code making it into the shell code,
confusing the shell parser.
