Remove the use of the cache for single-arch container images

This is a partially revert of
https://cos-review.git.corp.google.com/c/cos/tools/+/45593.

List of container images are single-arch and don't benefit much from the
caching stretagy. Using `docker build` without caching also helps to
generate provenance and SBOMs natively.

The list is:

cos_gpu_installer_v1
cos_ova_converter
cos_gpu_config_builder
cos_gpu_driver_builder
cos_kernel_devenv
