tests: use shorter labels in chainlint.sed for AIX sed

avar · gitster · commit a3c4c8841caa · 2018-08-27T14:07:18.000-07:00
Improve the portability of chainlint by using shorter labels. On
AIX sed will complain about:

    sed: 0602-417 The label :hereslurp is greater than eight
    characters

This, in combination with the previous fix to this file makes
GIT_TEST_CHAIN_LINT=1 (which is the default) working again on AIX
without issues, and the "gmake check-chainlint" test also passes.
