Switch to use bundled <linux/fcntl.h>

* bundled/linux/include/uapi/linux/fcntl.h: New file, copied from
headers_install'ed Linux kernel v5.11.
* bundled/Makefile.am (EXTRA_DIST): Add it.
* configure.ac (AC_CHECK_TYPES): Remove struct flock, struct flock64,
struct __kernel_flock, struct __kernel_flock64, struct f_owner_ex,
and struct __kernel_f_owner_ex.
* src/f_owner_ex.h: Remove.
* src/flock.h: Likewise.
* src/Makefile.am (libstrace_a_SOURCES): Remove f_owner_ex.h
and flock.h.
* src/fcntl.c: Include <linux/fcntl.h> instead of "flock.h".
(print_struct_flock64, printflock64, printflock): Replace
struct_kernel_flock64 with struct flock64.
* src/fetch_struct_flock.c: Include <linux/fcntl.h> instead of "flock.h".
Replace struct_kernel_flock64 with struct flock64 and
struct_kernel_flock with struct flock.
* src/file_handle.c: Include <linux/fcntl.h>.
* src/open.c: Likewise.
* src/open_tree.c: Likewise.
* src/statx.c: Likewise.
* src/link.c: Include <linux/fcntl.h> instead of <fcntl.h>.
* src/xlat/at_flags.in: Add #unconditional, remove fallback definitions.
* src/xlat/f_owner_types.in: Likewise.
* src/xlat/f_seals.in: Likewise.
* src/xlat/fcntlcmds.in: Likewise.
* src/xlat/name_to_handle_at_flags.in: Likewise.
* src/xlat/open_tree_flags.in: Likewise.
* src/xlat/fdflags.in: Add #unconditional.
* src/xlat/lockfcmds.in: Likewise.
* src/xlat/notifyflags.in: Likewise.
* tests/fcntl-common.c: Include <linux/fcntl.h> instead of "flock.h",
do not include "f_owner_ex.h", always define and invoke test_f_owner_ex,
assume <linux/fcntl.h> defines all its types and constants,
replace struct_kernel_flock64 with struct flock64,
struct_kernel_flock with struct flock, and
struct_kernel_f_owner_ex with struct f_owner_ex.
* tests/fcntl.c (test_flock64_undecoded): Replace struct_kernel_flock64
with struct flock64.
* tests/fcntl64.c (test_flock64_lk64): Likewise.
* tests/openat2.c: Include <linux/fcntl.h>,  assume it defines
all its types and constants.
