scripts/symbolize.py: accept -d <ELF_file> in addition to -d <dir>

The -d option of symbolize.py normally expects one or more directories,
where the script will look for ELF files (TEE or TA, depending on the
input dump). For convenience, let's also accept paths to the actual ELF
files. Previously, the script would just ignore file arguments and
silently fail to resolve stack traces.
