perf beauty: Fix AT_EACCESS undeclared build error for system with kernel versions lower than v5.8

In the environment of ubuntu 20.04 (the version of kernel headers is
5.4), there is an error in building perf:

    CC      trace/beauty/fs_at_flags.o
  trace/beauty/fs_at_flags.c: In function ‘faccessat2__scnprintf_flags’:
  trace/beauty/fs_at_flags.c:35:14: error: ‘AT_EACCESS’ undeclared (first use in this function); did you mean ‘DN_ACCESS’?
     35 |  if (flags & AT_EACCESS) {
        |              ^~~~~~~~~~
        |              DN_ACCESS
  trace/beauty/fs_at_flags.c:35:14: note: each undeclared identifier is reported only once for each function it appears in

commit 8a1ad4413519b10f ("tools headers: Remove now unused copies of
uapi/{fcntl,openat2}.h and asm/fcntl.h") removes fcntl.h from tools
headers directory, and fs_at_flags.c uses the 'AT_EACCESS' macro.

This macro was introduced in the kernel version v5.8.  For system with a
kernel version older than this version, it will cause compilation to
fail.
