Subject: test-chmtime: work around Windows limitation
X-Git-Tag: v1.6.4-rc0~63^2~9

test-chmtime: work around Windows limitation

Windows has problems changing the mtime when the file is write protected,
even by the owner of said file.

Add a Windows-only workaround to change the mode if necessary before
trying to change the mtime.
