Update to v5.7 kernel headers.

Kernel headers coming from:

Git: https://android.googlesource.com/kernel/common/
Branch: android-mainline
Tag: android-mainline-5.7

Update the generate_uapi_headers.sh where the types.h file is now in
the right place, but kvm.h is not.

Test: Booted cuttlefish/bonito.
Test: Ran bionic-unit-tests on cuttlefish/bonito.
