Enable CompileTime, except for tests

CompileTime reports work in a BEGIN block that has effects beyond the
program, such as I/O and assignments to %ENV, which go wrong in a binary
that B::C compiles.  Nothing in bin/ or lib/ does that.  Every report is
in a test, which writes its fixtures and sets HOME in a BEGIN block
before the SUT loads, because the SUT reads them as it loads.  No
compiled binary is made of a test, so the hook leaves this policy out
for t/, as it does RequireLocalizedPunctuationVars.
