install-deps.sh: Make powertools repo case insensitive

It looks like CentOS 8.3 will see all repos converted to lower case and
this has been pre-empted in the CentOS stream repos so we need to be
able to enable a repo called 'PowerTools' or 'powertools'

See https://git.centos.org/rpms/centos-repos/c/b759b17
