*Actually* test that bug 20011110.104 is fixed.

Bug ID 20011110.104 (RT #7896) was fixed by commit 2f173a711df6278f in Nov
2001, but the test that commit added never actually tested this.

The initial problem was that the new code, as written, used C<stat>,
intending that to call File::stat::stat(). However the refactoring of the
test script (all part of the same commit) from C<use File::stat;> to
C<use_ok( 'File::stat' );> (not in a BEGIN block) intentionally eliminated
the export of &File::stat::stat. This means that plain C<stat> is the
core builtin.

Fixing this as-is to File::stat::stat() won't help, as tests have
subsequently been added earlier in the script that trigger the autoloading
of Symbol by File::stat (commit 83716b1ec25b41f2 in Feb 2002). Moving the
tests earlier won't help now that the test uses File::Temp, as that uses
IO::Seekable which uses IO::Handle, which unconditionally loads Symbol.

The simplest solution seems to be to move the test to its own file.
