Makefile: fix whitespace in first $(E) argument

When silent make rules are enabled, we use special format
to inform what is going on, like this

$(E) "  ACTION  " files

We maintain specific whitespace around ACTION so different ones
are aligned nicely. Fix two places that were not aligned to the rest.
