[PATCH v3 07/13] livepatch/klp-build: fix shellcheck complaints

[Joe Lawrence]

Fix or suppress the following shellcheck warnings:

  In klp-build line 57:
        command grep "$@" || true
                               ^--^ SC2317 (info): Command appears to be 
unreachable. Check usage (or ignore if invoked indirectly).

Fix the following warning:

  In klp-build line 565:
                local file_dir="$(dirname "$file")"
                        ^------^ SC2034 (warning): file_dir appears unused. 
Verify use (or export if used externally).
