Wrap the remap_file_pages syscall

Wrap the remap_file_pages syscall

The remap_file_pages() system call is used to create a nonlinear
mapping, that is, a mapping in which the pages of the file are
mapped into a nonsequential order in memory.  It is deprecated
but in some cases it may still be used.  LTP remap_file_pages01
and remap_file_pages02 test-cover it.

Declare a remap_file_pages wrapper in priv_syswrap-linux.h
and hook it for {amd64,arm,arm64,mips64,ppc32,ppc64,riscv64,s390x\
,x86}- linux using LINX_ with PRE handler in syswrap-linux.c
