Martin Kaiser e1c19cd376 perf test: Fix "trace summary" test for musl-based systems
The trace summary test calls /bin/true and filters for open, read and
close events. These events are coming from shared library loads.

On a musl system, the loader and libc may point to the same file. true
needs only libc, no further shared libraries are loaded at startup. The
test fails since no open, read and close events are captured.

  root@host:~# ldd /bin/true
	/lib/ld-musl-riscv64.so.1 (0x3fb8882000)
	libc.so => /lib/ld-musl-riscv64.so.1 (0x3fb8882000)

  root@host:~# file /lib/ld-musl-riscv64.so.1
  /lib/ld-musl-riscv64.so.1: symbolic link to /usr/lib/libc.so

  root@host:~# strace -f /bin/true
  execve("/bin/true", ["/bin/true", ...], ... /* 18 vars */) = 1
  set_tid_address(0x3fa1f7bf70)           = 330
  mprotect(0x2ad6b8e000, 12288, PROT_READ) = 0
  exit_group(0)                           = ?
  +++ exited with 0 +++

Run "cat /dev/null" instead of "true". This creates the required events
regardless of the C library and it works for cat from busybox or from
coreutils.
