tools headers UAPI: Sync asm-generic/mman-common.h with the kernel
To pick the changes from:
Fixes: 4ca9b3859dac14bb ("mm/madvise: introduce MADV_POPULATE_(READ|WRITE) to prefault page tables")
That result in these changes in the tools:
$ tools/perf/trace/beauty/madvise_behavior.sh > before
$ cp include/uapi/asm-generic/mman-common.h tools/include/uapi/asm-generic/mman-common.h
$ tools/perf/trace/beauty/madvise_behavior.sh > after

I.e. now when madvise gets those behaviours as args, it will be able to
translate from the number to a human readable string.
This addresses the following perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman-common.h' differs from latest version at 'include/uapi/asm-generic/mman-common.h'
