Avoid using keyword restrict as variable name which causes error with gcc 5.x:

| hugeutils.c: In function '__lh_hugetlbfs_setup_env':
| hugeutils.c:304:40: error: expected identifier or '(' before 'restrict'
|    char *p, *tok, *exe, buf[MAX_EXE+1], restrict[MAX_EXE];
|                                         ^
