mbedtls/platform.h: Avoid potential macro redefinition warnings.

Some identifiers (e.g. mbedtls_free) can name either functions or
macros depending on configuration settings.  For those that turn out
to name macros, first clear out any existing macro definitions to
accommodate possible unconditional bulk symbol renaming.  (There
remains no standard provision for such renaming, but it's nevertheless
straightforward enough to do as desired, particularly with this change
in place.)
