perf trace beauty fcntl: Fix build with older kernel headers

Browse Source 
Toolchains with older kernel headers that do not include upstream commit
c75b1d9421 ("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: 9c47f66748 ("perf trace beauty fcntl: Basic 'arg' beautifier")
