crypto/aesni_gcm: check dependency version with meson

The aesni_mb driver and the aesni_gcm driver both require the same version
of the IPSec_MB library, but only the former has a check of the library
found by meson to see if it's the correct version. Add a similar check to
the aesni_gcm library's meson.build file, so that the auto-detection of
dependencies works correctly.
