base.bbclass: add dependency on pseudo from do_prepare_recipe_sysroot
do_prepare_recipe_sysroot may perform groupadd, which requires pseudo.
However, do_prepare_recipe_sysroot does not depend on pseudo explicitly,
which sometimes causes a build error when building a recipe that adds
groups.
This issue only occurs when executing do_prepare_recipe_sysroot for a
recipe that adds groups before finishing a task that depends on pseudo
for a recipe that doesn't add groups.
