Remove __ASSUME_F_GETOWN_EX.
This patch removes __ASSUME_F_GETOWN_EX now it can be assumed to be true unconditionally. Tested x86_64 that disassembly of installed shared libraries is unchanged by this patch. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_F_GETOWN_EX): Remove macro. * sysdeps/unix/sysv/linux/fcntl.c: Do not include <kernel-features.h>. (miss_F_GETOWN_EX): Remove variable or macro. (do_fcntl): Do not check miss_F_GETOWN_EX. (do_fcntl) [!__ASSUME_F_GETOWN_EX]: Remove conditional code.
