Change android V vintf level from 9 to 202404

Without this change to libvintf, changing the compatibility level in
compatibility_matrix.202404.xml to `202404` caused a build failure
because the value was unknown to libvintf. See https://android-review.git.corp.google.com/c/platform/system/libvintf/+/2903469

NO_IFTTT=not adding a new level, just changing the value of existing one

Test: atest libvintffm_test vintf_object_test libvintf_test
