scripts/sbom: catch ValueError from malformed shell quoting

parse_inputs_from_commands() only caught CmdParsingError and IndexError
when dispatching to command parsers, but several parsers call
shlex.split() internally, which raises ValueError on malformed shell
quoting (e.g. an unterminated quote). This exception was not caught,
so a single malformed build command would abort SBOM generation
entirely, even with fail_on_unknown_build_command=False, defeating the
purpose of tolerant mode.

The issue was found while reviewing the exception handling around the
saved-command parser after running its existing tests. It can be
reproduced with:

    parse_inputs_from_commands('gcc "unterminated',
                               fail_on_unknown_build_command=False)

Catch ValueError alongside CmdParsingError and IndexError so such
commands are logged as a warning/error and skipped instead of aborting
the whole run.

Add tests covering malformed shell quoting and a missing positional
argument.
