realpath(): Properly fail "." or ".." components after non-directories.

If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.

Also, put the check for non-directories after lstatting the previous
component instead of when the empty component (consecutive or trailing
slashes) is detected, saving an lstat() call and some lines of code.

Always install pkg.conf. Don't depend on MK_PKGBOOTSTRAP.

This file is used by pkg(8) from ports as well. Someone may
choose to not install pkg(7) but still want to consume
official packages by building or installing pkg(8) manually.
