tools headers UAPI: Update tools's copy of mman.h headers

To pick up the changes from:

  8aa3c927ec10 ("mm/mmap: move common defines to mman-common.h")
  22fcea6f85f2 ("mm: move MAP_SYNC to asm-generic/mman-common.h")
  0bf5f9492389 ("mm: fix the MAP_UNINITIALIZED flag")

To address the following perf build warnings:

  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'
  diff -u tools/include/uapi/asm-generic/mman-common.h include/uapi/asm-generic/mman-common.h
  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman.h' differs from latest version at 'include/uapi/asm-generic/mman.h'
  diff -u tools/include/uapi/asm-generic/mman.h include/uapi/asm-generic/mman.h

That ends up just moving a bit the auto-generated code->string tables:

  $ tools/perf/trace/beauty/mmap_flags.sh > before
  $ cp include/uapi/asm-generic/mman.h tools/include/uapi/asm-generic/mman.h
  $ cp include/uapi/asm-generic/mman-common.h tools/include/uapi/asm-generic/mman-common.h
