Compare existing ABI dump list with LSDUMP_PATHS

This commit fixes the check for redundant files in prebuilts/abi-dumps.
Some ABI dump file names are different from the module names. The list
of existing files should be compared with LSDUMP_PATHS which are the
files generated by soong.

This commit also adds the check for the files in
prebuilts/abi-dumps/platform.
