Fix corruption in ARGF.inplace
Extension string stored in `ARGF.inplace` is created using an api
designed for C string constants to create a Ruby string that
points at another Ruby string. When the original string is swept,
the extension string gets corrupted.
Reproduction script (on MacOS):
```ruby
#!/usr/bin/ruby -pi.bak
BEGIN {
GC.start(full_mark: true)
arr = []
1000000.times do |x|
arr << "fooo#{x}"
end
}
puts "hello"
```
