[PATCH] perf trace beauty fcntl: Fix build with older kernel headers

[Florian Fainelli <florian.fainelli@broadcom.com>]

Toolchains with older kernel headers that do not include upstream commit
c75b1d9421f80f4143e389d2d50ddfc8a28c8c35 ("fs: add fcntl() interface for
setting/getting write life time hints") will now fail to build perf due
to missing definitions for
F_GET_RW_HINT/F_SET_RW_HINT/F_GET_FILE_RW_HINT/F_SET_FILE_RW_HINT.

Provide a fallback definition for these when they are not already
defined.

Fixes: 9c47f6674838 ("perf trace beauty fcntl: Basic 'arg' beautifier")
