config.sh: Inhibit ldconfig cache generation unit

The ldconfig cache generator runs on first boot and attempts to
read the whole image into memory, which eats gigabytes of RAM and
slows the boot down by half a minute. This is unnecessary for
images being booted unmodified.

Thus, create the necessary dot files to inhibit their runs.
