Update copyright dates not handled by scripts/update-copyrights.

Update copyright dates not handled by scripts/update-copyrights.

I've updated copyright dates in glibc for 2015.  This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files.  Apart from the files updated
last time (of which sotruss.ksh had moved to sotruss.sh during the
year) this also updates nptl/version.c (missed from 2006 until
October) and sysdeps/unix/sysv/linux/lddlibc4.c (missed since 2009).
