[Buildroot] [PATCH] package/mbedtls: use pre-configure, not post-patch, hooks to configure

[Yann E. MORIN]

Currently, we use post-patch hooks to apply our configuration settings.
This works, but this is semantically wrong; post-patch hooks are there
to amend the source code to actually fix it (i.e. because it can't be
done with a patch for example).

Configuring the package, on the other hand, belong to the configure
step, and if we need to tweak the source code for configuration
purposes, this should be done in pre-configure hooks.
