Fix buglets in gdb.trace/tspeed.{exp,c}

When trying to run gdb.trace/tspeed.exp, I get:

ERROR: can't read "ipalib": no such variable
    while executing
"gdb_load_shlib $ipalib"
    (procedure "prepare_for_trace_test" line 5)

This problem seems to come from commit

    c708f4d256f ("gdb: Don't call gdb_load_shlib unless GDB is running")

which moved the gdb_load_shlib call in prepare_for_trace_test.  In order
to access the ipalib variable, we need to declare "global ipalib" first.

Then, this test uses nowarnings, for no good reason I could find.  We
can remove that and fix the two trivial warnings that appear:

/home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.trace/tspeed.c: In function 'main':
/home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.trace/tspeed.c:87:16: warning: too many arguments for format [-Wformat-extra-args]
        printf ("Negative times, giving up\n", max_iters);
                ^
/home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.trace/tspeed.c:99:7: warning: implicit declaration of function 'sleep' [-Wimplicit-function-declaration]
       sleep (1);  /* set post-run breakpoint here */
       ^

gdb/testsuite/ChangeLog:

	* gdb.trace/tspeed.exp: Remove nowarnings.
	(prepare_for_trace_test): Declare "global ipalib".
	* gdb.trace/tspeed.c: Include unistd.h.
	(main): Remove superfluous printf argument.
