records: Adjust 'record-abi-mismatch-error' arguments. 

Previously, 'display-error' (as used by 'warn-about-load-error', for
instance) would be called with a wrong number of arguments when a
'record-abi-mismatch-error' was caught:

  warning: failed to load '(gnu tests install)':
  Backtrace:
  [...]
  ERROR: In procedure display-error:
  Wrong number of arguments to #<procedure display-error (_ _ _ _ _ _)>

Now you get warnings and error reports as intended:

  warning: failed to load '(gnu tests install)':
  In procedure abi-check: <openssh-configuration>: record ABI mismatch; recompilation needed
  warning: failed to load '(gnu tests ssh)':
  In procedure abi-check: <openssh-configuration>: record ABI mismatch; recompilation needed

* guix/records.scm (print-record-abi-mismatch-error): Remove.
Remove top-level call to 'set-exception-printer!'.
(abi-check): Use arguments as expected by 'display-error'.
