Cygwin: drop objcopy .gnu_debuglink juggle
Prior to 591fec858d01 ("Cygwin: decouple cygheap from Cygwin DLL")
the .cygheap section was required to stay the last section in the
final binary. That required some juggling with objcopy to make
sure the .gnu_debuglink section is prior to the .cygheap section
in the final DLL.
This isn't required anymore, so just drop it.
