Bug 250731: lang/jruby: File.stat and File.lstat return incorrect values
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250731

--- Description ---
I tried jruby-9.2.5.0.

Wrong result by jruby:

```
% jruby -e 'p File.lstat
"/usr/local/share/jruby/lib/ruby/gems/shared/gems/rubygems-update-3.1.4"'
#<File::Stat dev=0xffffffffe2d119e8, ino=762223326, mode=0110572, nlink=6,
uid=0, gid=2, rdev=0x0, size=721299000, blksize=721299000, blocks=1604023633,
atime=1970-01-01 13:41:17 +0900, mtime=1970-01-01 09:00:00 +0900,
ctime=1992-11-09 17:50:01 +0900, birthtime=2020-10-30 11:07:13 +0900>
```

Expected result:

```
% ruby27 -e 'p File.lstat
"/usr/local/share/jruby/lib/ruby/gems/shared/gems/rubygems-update-3.1.4"'
#<File::Stat dev=0x2d6e9adee2d119e8, ino=430458, mode=040755, nlink=2, uid=0,
gid=0, rdev=0xffffffffffffffff, size=2, blksize=131072, blocks=1,
atime=2020-10-30 11:07:13.721299 +0900, mtime=2020-10-30 11:07:13.721299 +0900,
ctime=2020-10-30 11:07:13.721299 +0900, birthtime=2020-10-30 11:07:13.721299
+0900>
```

This will determine that there is a "path problem" and will fail to update or
install `jgem`.

```
