Thanks both.

The thing is that the checks for rstan-based objects *are*
conditional. This is actually failing on the tests for brms-based
objects, which import methods from rstan. I do test to see whether brms
is available or not.
I agree with Ivan's diagnosis that something has happened to the
rstan installation which leaves brms available but rstan somehow
(despite the fact that it is a hard dependency for brms) missing ...
I will ask the CRAN maintainers for guidance.

I'm noticing that despite broom.mixed having Suggests: rstan and it
being seemingly unable to load, you don't get a NOTE for the missing
dependency:
checking package dependencies ... NOTE
Packages suggested but not available for checking: 'dotwhisker',
'glmmADMB'
At that stage, R CMD check verifies that at least one of the libraries
contains file.path(PACKAGE_NAME, 'DESCRIPTION'). Later, something else
needs a valid rstan/Meta/package.rds. (There are also tests for links
between help pages, but they don't stop the check.) While running the
tests, methods:::.requirePackage actually tries to load the namespace
using require() -> ... -> loadNamespace(), which fails.

Having only the following files left from a valid 'rstan' installation,
I can make R CMD check broom.mixed_0.2.9.5.tar.gz reach the same error
as you're getting:
rstan
rstan/Meta
rstan/Meta/package.rds
rstan/DESCRIPTION
Something must have happened on the Fedora machine.
