docker: clang-android: Update to r450784
kernel/common will be using this version shortly:
https://android-review.googlesource.com/c/kernel/common/+/2032664
https://android-review.googlesource.com/c/kernel/common/+/2032665
https://android-review.googlesource.com/c/kernel/common/+/2032666
For the kernel, this fixes a crash with -fcf-protection=branch -mfentry -pg, which will be visible with CONFIG_X86_KERNEL_IBT=y and CONFIG_FUNCTION_TRACER=y.
I am depending on this version bump for a series that I'll link once it is sent, so it would be nice if the images could be updated as soon as this change is merged to minimize the chance of breakage for both our CI as well as LKFT's.
