Feature #10295: [PATCH] io.c (fptr_finalize): free memory (before GC sweep)

Description

Note: just committed r47712 which was trivial.
This passes tests, too, but I would appreciate another set of eyes
in case there's a subtle finalization issue I'm missing.

This releases memory on explict calls to rb_io_close,
reducing pressure on the GC.

Final massif snapshot shows reduced heap usage after RubyGems load
(valgrind --tool=massif ./ruby -e exit)

before:
mem_heap_B=4821992
mem_heap_extra_B=1302952

after:
mem_heap_B=4791056
mem_heap_extra_B=1192440
