[Buildroot] [PATCH v3] libostree: override path to gpg-error-config

[Marcus Folkesson <marcus.folkesson@gmail.com>]

libostree has begun to use `gpg-error-config` in their configuration
script.
Point out gpg-error-config in staging dir to avoid using the one
installed on the host system.

Fixes:

Notes:
    v2:
    	- override GPG_ERROR_CONFIG instead of ac_cv_path_GPG_ERROR_CONFIG
    v3:
    	- depend on libgpg-error
