[PATCH 11/30] nptl: Remove lseek from libpthread

Please make the newer versions compat symbols (not the older ones), then
we don't have to add a GLIBC_2.34 symbol version.
lseek64@GLIBC_2.1(libc.so.6) is valid for old glibc too, but
lseek64@GLIBC_2.2(libpthread.so.0) could cause load failures.

Thanks,
