Eric Pouech a4b206b384 dbghelp: Handle the case where loader isn't what WINELOADER reports. 
use case, in a WoW setup:
	wine programs/winedbg/winedbg.exe.so notepad.exe
where both winedbg and notepad are 64bit exec:s

in this case, dbghelp (loaded from winedbg) reads '<...>/wine' from WINELOADER
windows env block inside notepad
(but the unix env block is correctly set to wine64 by the tweak in
ntdll/unix/loader.c)

as a consequence dbghelp doesn't get the ELF information (it tries to read 32bit
ELF entities, and fails); hence misses all the loaded ELF libraries
winedbg's command 'info share' only reports the PE modules

note: the 'dual' case
  wine64 programs/winedbg/winedbg.exe.so c:\\windows\\syswow64\\notepad.exe
  where winedbg is a 64bit exec and notepad a 32bit
  shows the same failures

workaround this in dbghelp by tweaking the value of WINELOADER whether
the debuggee is 32 or 64bit
