Fixes: [47175] - services - Check the binary before setting WOW64 entry.
Fixes: [50431] - services - Dont write WOW64 for 64bit binaries.

# ImagePath doesn't need to have a Full path
# - already loads by looking up the relation path (%PATH%)
# - Problem is the WOW64 in the service record.

# When using win32 prefix, works as expected since the WOW64 flag isn't set
#  and uses the 32bit service dll.
