linuxkm: various tweaks: 

* configure.ac: in linuxkm-lkcapi-register section, force ENABLED_AESGCM_STREAM=yes if ENABLED_AESGCM is yes and there is asm or FIPS in the picture.
* linuxkm/module_hooks.c: in updateFipsHash(), if DEBUG_LINUXKM_PIE_SUPPORT || WOLFSSL_LINUXKM_VERBOSE_DEBUG, print the base16 hash to the kernel log.
* linuxkm/lkcapi_glue.c:
  * implement KATs for AES-CBC, AES-CFB, and AES-GCM.
  * clean out extraneous code and macro usage inherited from test/test.c.
  * add post-registration crypto_tfm_alg_driver_name() tests for AES-CBC, AES-CFB, and AES-GCM.
