Remove __ASSUME_SOCK_CLOEXEC / SOCK_CLOEXEC conditionals in Linux-specific code.
This patch removes conditionals on __ASSUME_SOCK_CLOEXEC, and on SOCK_CLOEXEC being defined, in Linux-specific code, now that all supported Linux kernel versions can be assumed to have this functionality. (The macro is also used in OS-independent code and is not defined for Hurd.) Tested x86_64 that the disassembly of installed shared libraries is unchanged by this patch. * nptl/sysdeps/unix/sysv/linux/mq_notify.c: Do not include <kernel-features.h>. (init_mq_netlink): Remove conditional have_sock_cloexec definitions. Remove code conditional on have_sock_cloexec < 0. (init_mq_netlink) [!SOCK_CLOEXEC]: Remove conditional code. (init_mq_netlink) [!__ASSUME_SOCK_CLOEXEC]: Likewise. * sysdeps/unix/sysv/linux/opensock.c: Do not include <kernel-features.h>. (__opensock) [SOCK_CLOEXEC]: Make code unconditional. (__opensock) [!__ASSUME_SOCK_CLOEXEC]: Remove conditional code.
