Merge patch series "lib: uuid: fix uuid_str_to_le_bin() on 32-bit"

Heinrich Schuchardt <heinrich.schuchardt@canonical.com> says:

The lib_test_uuid_to_le and lib lib_test_dynamic_uuid tests fail on
32-bit systems. But we never caught this in our CI because we never
ran any of our C unit tests on 32-bit.

Enable CONFIG_UNIT_TEST on qemu_arm_defconfig.

hextoul() cannot convert a string to a 64-bit number on a 32-bit system.
Use the new function hextoull() instead.
