Fix 'local-eval' when the specified environment is a module

* module/ice-9/local-eval.scm (local-wrap): Fix the (module? e) case, to
  reference the expression 'x' instead of the non-existent variable
  'exp', as was previously done.  Also use quasisyntax instead of
  quasiquote, so that the introduced 'lambda' is an identifier instead
  of a bare symbol, so that this will work in modules that have rebound
  'lambda' to something else.

* test-suite/tests/eval.test (local-eval): Make sure to test both
  'local-eval' and 'local-compile' when the specified environment is a
  module.
