rsync-2.5.1 / updated syscall.c "const" patch

[John E. Malmberg]

Operating System: OpenVMS ALPHA V7.3
Compiler: Compaq C T6.5

Compiler switches: /WARN=ENABLE=(LEVEL4, QUESTCODE)

syscall.c is missing the "const" qualifiers for several of it's 
functions.  This patch should supercede the previous patch I submitted.

This was discovered while working on resovling the conflicts between 
signed and unsigned values.
