binutils: move packaging of gprofng static lib into common .inc

Commit f72fd51e (binutils: package static libs from gprofng) added
corresponding FILES:${PN}-staticdev entry to the main .bb recipe.
But binutils-cross-canadian fails with exactly the same QA issue,
hence move FILES:${PN}-staticdev to the common shared .inc file.
