Tools: More support for "VMware Tools for Linux-arm64"

Preliminary touch-ups in the main branch to support the upcoming upstreaming
of the "VMware Tools for Linux-arm64" build code.

bora-vmsoft/vgauth/service/servicePosix.c:
  The glibc on arm64 does not have <sys/io.h>.  It makes sense because I/O
  ports are an x86-ism (for more details, sees
   https://bugzilla.redhat.com/show_bug.cgi?id=1116162#c1 ).  Instead of
  making the inclusion conditions more complex, It was noticed that none
  of the symbols defined in <sys/io.h> and <sys/sysinfo.h> are used in
  this C file.  So these inclusions are not necessary.
