syswrap-linux.c (sys_execveat): Define path as const HChar *

Like buf, path (ARG2) is a const HChar *
Prevents a gcc warning: assignment discards 'const' qualifier from
                        pointer target type [-Wdiscarded-qualifiers]
13328 |                        path = buf;
      |                             ^
