util: add bash completion script

Add a bash script for the flashrom CLI that auto-completes the command
sequence. The script is generated from a template by substituting a
list of enabled programmers. It requires an extra `bash-completion`
package to work, but, fortunately, it's installed on most systems.

Build system changes:

  meson:
   provide option `bash_completion` to determine if the script should
   be installed (depends on option `classic_cli`).

  makefile:
   make a list of enabled programmers (by using CONFIG_* variables)
   to do substitution manually
