build: fix the description of the named_install step

Replace the description of the named_install step from
"Install {s} to zig-cache/bin" to "Copy {s} to prefix path".  The latter
has been adapded from the description of the builtin install step.

Ad an empty line before the build_step variable, in order to improve
readability.

Closes #213
