omarchy-ane-dkms: check() passes on kernels with the in-tree ANE driver

dkms.conf sets BUILD_EXCLUSIVE_CONFIG="!CONFIG_DRM_ACCEL_ANE", so on a kernel
that ships the in-tree driver "dkms build" exits 77 and builds nothing.
check() treated that as a failure, and makepkg stopped in check().

check() now takes exit 77 as "no DKMS build" when the kernel's config sets
CONFIG_DRM_ACCEL_ANE, and prints it. After a build it lists ane.ko and
ane_t6021.ko from the DKMS tree. Every other dkms exit status still fails
check().
