libtool: Include _CRTIMP in _putenv() declaration in EXE wrapper sources.

Re-declaring _putenv() without _CRTIMP in strict ANSI mode when using
MinGW resulted in a warning because of a conflict with the previous
declaration that did use _CRTIMP.

Simply add _CRTIMP to our declaration to avoid it.

* build-aux/ltmain.in (func_emit_cwrapperexe_src): Add _CRTIMP to
_putenv() declaration.
