Fix macro infinite recursion test to not trigger warning about semicolon in expr

Browse Source 
The test cases for issue 41731 are about infinite macro recursion that
incorporates `print!` and `println!`. However, they also included
trailing semicolons despite expanding to expressions; that isn't what
these particular test cases are designed to test.

Eliminate the trailing semicolons, to simplify future work on removing
this special case. Every *other* macro that expands to a semicolon in an
expression is a test case for that specifically.
