eval.c (ruby_setup): disable THP on Linux
Transparent Huge Pages (THP) decrease the effectiveness of
CoW-friendly GC because it decreases page granularity. That is,
a forked process dirtying one bit of CoW-shared memory can
trigger a copy of a huge page (2MB on x86-64) instead of a smaller,
standard page (4K).
* eval.c (ruby_setup): disable THP on Linux
[ruby-core:86651] [Feature #14705]
