[PATCH 3/3] Cygwin: avoid GCC 10 error with -Werror=narrowing

[Jon Turney]

../../../../src/winsup/cygwin/pinfo.cc: In member function 'DWORD pinfo::status_exit(DWORD)':
../../../../src/winsup/cygwin/ntdll.h:21:68: error: narrowing conversion of '-536870295' from 'NTSTATUS' {aka 'int'} to 'unsigned int' [-Wnarrowing]
../../../../src/winsup/cygwin/pinfo.cc:136:10: note: in expansion of macro 'STATUS_ILLEGAL_DLL_PSEUDO_RELOCATION'

../../../../src/winsup/cygwin/sigproc.cc: In member function 'DWORD child_info::proc_retry(HANDLE)':
../../../../src/winsup/cygwin/ntdll.h:21:68: error: narrowing conversion of '-536870295' from 'NTSTATUS' {aka 'int'} to 'unsigned int' [-Wnarrowing]
../../../../src/winsup/cygwin/sigproc.cc:1120:10: note: in expansion of macro 'STATUS_ILLEGAL_DLL_PSEUDO_RELOCATION'

NT error statuses seem to be variously DWORD (unsigned) or NTSTATUS
(signed)?  So use the one which doesn't cause problems here.
