posix: Consolidate register-atfork
Both htl and nptl uses a different data structure to implement atfork
handlers. The nptl one was refactored by 27761a1042d to use a dynarray
which simplifies the code.
This patch moves the nptl one to be the generic implementation and
replace Hurd linked one. Different than previous NPTL, Hurd also uses
a global lock, so performance should be similar.
Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for
i686-gnu.
