scripts/get_abi.pl: avoid creating duplicate names
The file the Documentation/ABI/testing/sysfs-class-power has
voltage_min, voltage_max and voltage_now symbols duplicated.
They are defined first for "General Properties" and then for
"USB Properties".
This cause those warnings:
get_abi.pl rest --dir $srctree/Documentation/ABI/testing:26933: WARNING: Duplicate explicit target name: "abi_sys_class_power_supply_supply_name_voltage_max".
get_abi.pl rest --dir $srctree/Documentation/ABI/testing:26968: WARNING: Duplicate explicit target name: "abi_sys_class_power_supply_supply_name_voltage_min".
get_abi.pl rest --dir $srctree/Documentation/ABI/testing:27008: WARNING: Duplicate explicit target name: "abi_sys_class_power_supply_supply_name_voltage_now".
And, as the references are not valid, it will also generate
warnings about links to undefined references.
Fix it by storing labels into a hash table and, when a duplicated
one is found, appending random characters at the end.
