load.c: make fstrings from C strings sooner

normal · normal · commit 42c2df993785 · 2017-04-27T03:16:39.000Z
The underlying string objects will become fstrings anyways,
so create the fstring directly from the C string to reduce
intermediate garbage.

* load.c (rb_provide, rb_provide): create fstring
