Configured process_madvise with upstream syscall number 



Fixing the syscall mapping which was done wrongly by
'commit f4ed7311 ("mm/madvise: introduce process_madvise()
syscall: an external memory hinting API")' by correcting the syscall
number.

unistd#close_range cts testcase is expecting errno as ENOSYS
because msm-5.4 does not support close_range syscall, but it
receives errno as EINVAL because process_madvise is configured
with 436 which is close_range syscall number which leads to
this cts testcase failure. Hence, configured process_madvise
with proper upstream syscall number to fix this cts failure.

Applications using process_madvise that are built with previous
headers needs to be rebuilt. Otherwise the program would not
work as expected.
