[PATCH v3] perf build: Raise minimum shellcheck version to 0.7.2

[Nicolas Schier <n.schier@avm.de>]

Raise the minimum shellcheck version for perf builds to 0.7.2, so that
systems with shellcheck versions below 0.7.2 will automatically skip the
shell script checking, even if NO_SHELLCHECK is unset.

Since commit 241f21be7d0f ("perf test perftool_testsuite: Use absolute
paths"), shellcheck versions before 0.7.2 break the perf build with
several SC1090 [2] warnings due to its too strict dynamic source
handling [1], e.g.:

  In tests/shell/base_probe/test_line_semantics.sh line 20:
  . "$DIR_PATH/../common/init.sh"
    ^---------------------------^ SC1090: Can't follow non-constant source. Use a directive to specify location.

Fixes: 241f21be7d0f ("perf test perftool_testsuite: Use absolute paths")
