time64: enable 64-bit time/file-offset flags for 32-bit nativesdk

Browse Source 
When SDKMACHINE is set to i686 or i586, nativesdk binaries are compiled
as 32-bit. Without -D_TIME_BITS=64 and -D_FILE_OFFSET_BITS=64, stat()
and time-related syscalls use 32-bit types, causing EOVERFLOW on
filesystems with large inode numbers (e.g. container overlay filesystems)
and Y2038 issues.

Add SDK_CC_ARCH appends for class-nativesdk:i686 and class-nativesdk:i586
using GLIBC_64BIT_TIME_FLAGS, mirroring how target architectures are
handled.

The existing GLIBC_64BIT_TIME_FLAGS:pn-glibc override only matches the
target recipe, not the class extended nativesdk-glibc, so an additional
pn-nativesdk-glibc override is needed here. This is required on
scarthgap but not on master/wrynose, because scarthgap carries glibc
2.39, which predates glibc commit a4ed0471d717 ("Always define
__USE_TIME_BITS64 when 64 bit time_t is used"). In 2.39 the header
redirect turns sigtimedwait into an alias of __sigtimedwait64, which
then collides with glibc's own weak_alias() and fails to assemble:

  Error: symbol '__sigtimedwait64' is already defined

Also exclude nativesdk-mingw-w64-runtime. The MinGW runtime provides the
Windows CRT rather than glibc, and _FILE_OFFSET_BITS=64 changes its
stat declarations. That causes conflicting declarations for wstat when
building the CRT itself.
