Subject: [PATCH] scripts/spdxcheck.py: fix C++ comment style detection

With the last commit to support the SuperH boot code files, we have the
following regression:

$ ./scripts/checkpatch.pl -f <(echo '/* SPDX-License-Identifier: MIT */')
WARNING: 'SPDX-License-Identifier: MIT */' is not supported in LICENSES/..
+/* SPDX-License-Identifier: MIT */

total: 0 errors, 1 warnings, 1 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or --fix-inplace.

/dev/fd/63 has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.

This is not obvious, but spdxcheck.py is launched in checkpatch.pl with :
    ...
    } elsif ($rawline =~ /(SPDX-License-Identifier: .*)/) {
        my $spdx_license = $1;
        if (!is_SPDX_License_valid($spdx_license)) {
            WARN("SPDX_LICENSE_TAG",
                 "'$spdx_license' is not supported in LICENSES/...\n" . \
                 $herecurr);
        }
    ...
    sub is_SPDX_License_valid {
        my ($license) = @_;
        ...
        my $status = `cd "$root_path"; echo "$license" |
                      python scripts/spdxcheck.py -`;
        ...
    }

The first chars before 'SPDX-License-Identifier:' are ignored.
This commit fixes this regression.
