[LTP] [PATCH] syscalls/chdir/chdir04.c: fix out-of-bounds write

[Tobias Jordan]

When UCLINUX is defined, line 156 will write to the TC[2].dname:
    #ifdef UCLINUX
        [...]
        TC[2].dname = bad_addr;
    #endif

However, TC[2] won't exist as it's only initialized when UCLINUX is
not defined and length of TC is implicit. Remove "#ifndef UCLINUX"
around initializer for TC[2].
