find: unknown predicate `-not -path '

We see this error on CircleCI builds: eg: https://app.circleci.com/pipelines/github/zulip/zulip/7488/workflows/7906c5d1-5032-47a1-88f3-60e79a9631d1/jobs/43293/parallel-runs/0/steps/0-114

find: unknown predicate `-not -path './bower_components/**' -not -path './node_modules/**' -not -path './vendor/**''
 
    Error running `['find', '/home/circleci/zulip', "-not -path './bower_components/**' -not -path './node_modules/**' -not -path './vendor/**'", '-type', 'f', '-name', '*.gcno', '', '-exec', 'gcov', '-pb', '', '{}', '+']`: Command '['find', '/home/circleci/zulip', "-not -path './bower_components/**' -not -path './node_modules/**' -not -path './vendor/**'", '-type', 'f', '-name', '*.gcno', '', '-exec', 'gcov', '-pb', '', '{}', '+']' returned non-zero exit status 1.

When running:

pip install codecov && codecov

Pinning the version of codecov==2.0.15 fixes this (since it doesn’t use find.)

We use buildpack-deps:bionic-scm as our base image for CI builds.

Our CI config file - https://github.com/zulip/zulip/blob/master/.circleci/config.yml

Let me know if you need any more details to debug this.

#217 removes find command entirely using python to do file searching and excluding. It can help here too because too many inconsistencies with find command and not supported on Windows.

Thanks for fixing this quickly!!
