PR31373: Deal with the removal of strlcpy() from linux 6.8
    
    The Linux 6.8 kernels removed strlcpy() with git commit d26270061a in
    January 2024.  All the kernel's strlcpy() uses were converted to
    strscpy().  Systemtap needed to do the same.  This is implemented in
    systemtap with a strlcpy macro in the runtime that translates the
    strscpy() return value into the equivalent strlcpy() value.
