testing: pass KPATCH_BUILD_OPTS to kpatch-test

Update the test/integration/Makefile to pass a KPATCH_BUILD_OPTS
variable to kpatch-test.  This allows the user better control over the
kpatch build process, for example, building non-atomic replace .ko files
on kernels that do support atomic-replace:

  % make integration KPATCH_BUILD_OPTS="--non-replace"
