E0132 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0132.rs

Error E0132 needs a span_label, updating it from:

error[E0132]: start function is not allowed to have type parameters
  --> src/test/compile-fail/E0132.rs:14:1
   |
14 | fn f<T>() {} //~ ERROR E0132
   | ^^^^^^^^^^^^

To:

error[E0132]: start function is not allowed to have type parameters
  --> src/test/compile-fail/E0132.rs:14:1
   |
14 | fn f<T>() {} //~ ERROR E0132
   | ^^^^^^^^^^^^ start function cannot have type parameters

Bonus: Underline just the type parameters

error[E0132]: start function is not allowed to have type parameters
  --> src/test/compile-fail/E0132.rs:14:1
   |
14 | fn f<T>() {} //~ ERROR E0132
   |     ^^^ start function cannot have type parameters
