Use sqlite-based cache by default, when available

[HonkingGoose]

Describe the proposed change(s).

Todos

• Figure out way to deal with "install time compilation".
• Let Renovate use the sqlite-based cache, if available.

Context

Rescuing an idea from getting lost in the Discussions. @viceice asked:

should we switch to the sqlite based cache by default if sqlite is available? it's much faster.

And @rarkins responded:

Yes but the install time compilation is unfortunately a problem for some
