chore(deps): Add libmagic as fallback for typecode-libmagic

ScanCode's typecode-libmagic Python library needs a fallback
on platforms that do not have the library plugin capability,
notably linux/aarch64.

The library performs a file check files with data in particular
fixed formats, trying to guess the proper file format to perform
the necessary operation.

In Ubuntu image, libmagic1 system library and file utility are
the fallback requirements.
