Update zts-report.py with additional tests

[behlendorf]

Motivation and Context

Enable the Fedora 32 builder by default and reduce the number of
known false positives resulting in ZTS failures. These tests should
be updated to be more reliable on all platforms and then removed
from the "maybe" list.

Description

The following test cases may still occasionally fail and are being
added to the "maybe" list for Linux until they can be updated to be
entirely reliable.

cli_root/zfs_rename/zfs_rename_002_pos.ksh
cli_root/zpool_reopen/zpool_reopen_003_pos.ksh
refreserv/refreserv_raidz

These 6 tests consistently fail only on Fedora 31+ are the failures
are related to the kernel rescanning the partition table on loopback
devices which is no longer reliable unless partprobe is used. In
order to enable the Fedora bot by default they are also being added
to the list until the tests can be updated.

rsend/rsend_010_pos
rsend/rsend_011_pos
