A bug has been introduced to the which package in CentOS Stream 8 which
causes it to fail when used with the following bash options:
set -u
set -o pipefail
Then, when running which we see the following output:
environment: line 1: _declare: unbound variable
As found by Pierre, this seems to be caused by the implementation of
which as a bash function which references an unbound variable
(_declare). It's tracked in Fedora by
https://bugzilla.redhat.com/show_bug.cgi?id=1944877#.
This change works around the issue by using the /usr/bin/which binary.
