[PATCH] Work around sed portability issue in t8006-blame-textconv

[Ben Walton <bwalton@artsci.utoronto.ca>]

In test 'blame --textconv with local changes' of t8006-blame-textconv,
using /usr/xpg4/bin/sed on Solaris as set by SANE_TOOL_PATH, an
additional newline was added to the output from the 'helper' script
driven by git attributes.

This was noted by sed with a message such as:
sed: Missing newline at end of file zero.bin.

In turn, this was triggering a fatal error from git blame:
fatal: unable to read files to diff

The git blame --textconv stdout was empty as a result of the error
condition above.  This caused the test to fail because the output
value differed from the expected result.

Use perl -p -e instead of sed -e to work around this portability issue
as it will not insert the newline.  This allows the git blame call to
complete at which point the output comparison is successful.
