[Bug #19289] Retain `ruby_abi_version` function
A few extension libraries, to hide all symbols except for necessary to
load, hardcode the symbols to be exported in symbol list files for
linker without even checking by `have_func`. As a workaround for such
libraries, retain `ruby_abi_version` symbol always even in released
versions for now.
