[OE-core] [PATCH 1/1] lib/oe/recipeutils: fix replace_dir_vars to return the correct variables

[Paul Eggleton]

If we sort by length of name here we get the variables we are interested
in first. I've tested this with all of the variables we care about (the
ones at the top of bitbake.conf) and it returns the right results.

This fixes the failures we've been seeing in the oe-selftest
test_recipetool_appendfile_* tests.
