vl53l0x driver is using an external library to build, located under:
ext/hal/st/lib/sensor/vl53l0x.
This library is expecting stdint.h lib to be available and to
secure this for driver library inclusion work, a stdint.h file
header check was done. This check was based on assumptions on possible
header names for stdint.h.
Due to recent renaming of the zephyr header files, this check was
returning a false positive, generating warning at compilation.
Rather than updated with new header names, remove this check, since
driver porting is completed and stdint.h inclusion is actually
done.
Fixes#10134
