[gentoo-portage-dev] [PATCH] search._xmatch: handle aux_get KeyError (525718)

[Zac Medico]

Since commit 55c8c8bc7a781e3f71ce92922eea64ad4cafce3c, emerge --search
can raise an unhandled KeyError if a pkg_desc_index contains a stale
package. Handle it with the same error message used for other aux_get
failures.

Fixes: 55c8c8bc7a78 ("Add emerge --search-index option.")
