tools: Update asm-generic/mman-common.h copy from the kernel

To get the defines introduced in the commit e8c24d3a ("x86/pkeys:
Allocation/free syscalls")

Silencing this perf build warning:

  Warning: tools/include/uapi/asm-generic/mman-common.h differs from kernel

Need to change 'perf trace' to beautify those syscalls, as soon as
booting with a kernel with it.
