Subject: [PATCH v4 03/14] tools, perf: make gfp_compact_table up to date

When updating tracing's show_gfp_flags() I have noticed that perf's
gfp_compact_table is also outdated. Fill in the missing flags and place a
note in gfp.h to increase chance that future updates are synced. Convert the
__GFP_X flags from "GFP_X" to "__GFP_X" strings in line with the previous
patch.
