Joe Lawrence 54268bfb3e integration: update gcc-static-local-var-4.test
The gcc-static-local-var-4.patch and test check that unmodified
functions that contain dynamic debugging printk's aren't incorrectly
included in the resulting livepatch .ko.

Note that on RHEL-7.7 ppc64le, the gcc-static-local-var-4.ko livepatch
module may include klp-relocation references to free_ioctx(), a function
that would match the above criteria.  These klp-relocation symbols are
OK as they are only used for referencing said functions, they are not
copies that the check should FAIL on.

Modify gcc-static-local-var-4.test in a few ways:

  - Use eu-readelf instead of readelf, which some versions have problems
    handling klp-relocations.

  - Set pipefail to catch any errors in the symbol table dump (missing
    elfutils, etc.)

  - Instead of a grep regex, use awk to string compare exact function
    and module names.  This avoids matching on .klp.sym prefixed
    klp-relocation symbols.

Fixes #1069.
