Subject: [PATCH 35/48] [gdb/testsuite] Add missing include in
 gdb.base/rtld-step.exp

On fedora rawhide, with test-case gdb.base/rtld-step.exp I get:
...
static-pie-static-libc.c: In function '_start':^M
static-pie-static-libc.c:1:22: error: \
  implicit declaration of function '_exit' [-Wimplicit-function-declaration]^M
    1 | void _start (void) { _exit (0); }^M
      |                      ^~~~~^M
compiler exited with status 1
  ...
UNTESTED: gdb.base/rtld-step.exp: failed to compile \
  (-static-pie not supported or static libc missing)
...

Fix this by adding the missing include.

Tested on aarch64-linux.
