hikey960: workaround: disable graphics driver preloading
As the Mali userspace binaries were built for Android 8.0,
when -ffixed-x18 was not guarteed to be used, which had been
ensured for Android versions newer than P for the shadow
call stack (SCS) feature.
For such old version vendor blob, there was a workaround
in com_android_internal_os_ZygoteInit.cpp which has been removed
now.

After that removal, there is a crash on libbluetooth_jni.so
reported as the issue here:
https://issuetracker.google.com/issues/302408537
As a workaround, disabling the preloading of them to avoid
the bluetooth crash issue.
Bug: 302408537
Test: bluetooth enabled by default after booted up
