graphics(weston-simple-egl): fix overlay detection for Adreno GLVND vendor JSON

The test previously detected overlay builds only when a file matching
/usr/share/glvnd/egl_vendor.d/*EGL_adreno.json existed. Some images use
the GLVND vendor filename 10_adreno.json instead, causing overlay builds
to be misclassified as base.

Update detection to scan common GLVND vendor directories and accept both
*adreno*.json and *EGL_adreno*.json patterns. Log the detected vendor
JSON path when overlay is present.
