melting-pot: give friendlier dep change output

ctrueden · ctrueden · commit dd4fd4847615 · 2022-10-26T12:04:44.000-05:00
The fact that the dependencies do not match since the last successful
build, and therefore the component build is going to be executed, is not
necessarily a bad thing. The word "mismatch" conveys something wrong;
let's instead just point out what's changed, more neutrally.
