Log Message:
make: clean up eat_dots for meta mode, part 2

At least on OpenBSD, "If the src and dst strings overlap, the behavior
is undefined" (since 2013-09-25), so rather use memmove instead.

Keep all other bugs for now, for example "/a/b//../" is reduced to
"/a/b/" instead of the correct "/a/", and for repeated "/././././" in
long paths, the performance is quadratic instead of linear.

Inline the two calls to eat_dots, turning the first into a two-liner.
