Skip gdb.base/many-headers.exp on Cygwin (submit independently)

When I first wrote this, I didn't have dumper.exe setup, so the
testcase would spend 10 minutes doing the mmap loop thing, and then it
wouldn't create a core dump anyhow.  But with dumper.exe around, the
testcase does generate the core dump, and it passes cleanly!  So just
skipping isn't right.  I'm inclined to just drop the patch.

I also wonder whether using native Win32 VirtualAlloc would be a lot
faster than Cygwin mmap...
