Extend helgrind suppression for _IO_*xsputn* FILE* state manipulation

Browse Source 
commit 7b5867b1f "helgrind reports false races for printfs using
mempcpy on FILE* state" extended the helgrind-glibc-io-xsputn
suppression by also covering mempcpy (instead of __GI_mempcpy).
The test added in that commit exposed a couple of other variants
of this suppression where _IO_*xsputn* called memcpy (instead of
mempcpy) and/or had an extra indirection/function in between.

Replace the two two suppressions with one that covers all cases
where _IO_*xsputn* *mem*cpy variants with possibly another ...
function in between.
