users-guide: Support both distutils and packaging

As noted in #23818, some old distributions (e.g. Debian 9) only include
`distutils` while newer distributions only include `packaging`.

Fixes #23818.

Use unsatisfiable for missing methods w/ defaults

When a class instance has an Unsatisfiable constraint in its context
and the user has not explicitly provided an implementation of a method,
we now always provide a RHS of the form `unsatisfiable @msg`, even
if the method has a default definition available. This ensures that,
when deferring type errors, users get the appropriate error message
instead of a possible runtime loop, if class default methods were
defined recursively.

Fixes #23816

packaging: Build manpage in separate directory to other documentation

We were installing two copies of the manpage:

* One useless one in the `share/doc` folder, because we copy the doc/
  folder into share/
* The one we deliberately installed into `share/man` etc

The solution is to build the manpage into the `manpage` directory when
building the bindist, and then just install it separately.

Fixes #23707

hadrian: Always canonicalize topDirectory

Hadrian's `topDirectory` is intended to provide an absolute path to the
root of the GHC tree. However, if the tree is reached via a symlink this

One question here is whether the `canonicalizePath` call is expensive
enough to warrant caching. In a quick microbenchmark I observed that
`canonicalizePath "."` takes around 10us per call; this seems
sufficiently low not to worry.

Alternatively, another approach here would have been to rather move the
canonicalization into `m4/fp_find_root.m4`. This would have avoided
repeated canonicalization but sadly path canonicalization is a hard
problem in POSIX shell.

Addresses #22451.
