man/man2/chmod.2: Document AT_SYMLINK_NOFOLLOW support in fchmodat(2)
Historically, Linux systems did not support the AT_SYMLINK_NOFOLLOW flag
to fchmodat(2). glibc added userspace emulation support in glibc 2.32,
and Linux gained native support in 6.5. See glibc.git 6b89c385d8bd
(2020-02-12; "io: Implement lchmod using fchmodat [BZ #14578]") and
linux.git 09da082b07bb (2023-07-27; "fs: Add fchmodat2()").
