[Buildroot] [PATCH] infra: /usr support: STAGING_DIR can be outside BASE_DIR

If the user sets a custom BR2_HOST_DIR, then STAGING_DIR is not under
BASE_DIR. The .pc/.la file fixup commands incorrectly made this assumption
and thus should be corrected.
Additionally, this patch rewords the comment in pkg-autotools that explains
the replacements.
