modpost: trim leading spaces when processing source files list

get_line() does not trim the leading spaces, but the
parse_source_files() expects to get lines with source files paths where
the first space occurs after the file path.

Fixes: 70f30cfe5b89 ("modpost: use read_text_file() and get_line() for reading text files")
