OK, direct the annoying traces to the output folder

Otherwise it was getting messy to distinguish between trace-events
and trace-<pid> in the .gitignore.

Now only the latest trace will be kept, with a fixed name.

[options="header"]
|===
|Name |Argument name | Description
|`-a` |`ARCH` | Run architecture `ARCH`.
|`-c` |`NCPUS` | Emulate `NCPUS` guest CPUs.
|`-D` | | Run GDB on the emulator itself.
|`-d` | | Run in debug mode, expect a GDB connection to guest.
|`-E` |`CMDSTR` | Replace the normal init with a minimal init that just evals
with given `CMDSTR` bash command string. Example:
`-E 'insmod /hello.ko;'`
|`-e` |`CLI_OPTIONS` | Pass an extra Linux kernel command line options,
and place them before the dash separator `-`.
Only options that come before the `-`, i.e. "standard"
options, should be passed with this option.
Example: `./run -a arm -e 'init=/poweroff.out'`
|`-f` |`CLI_OPTIONS` | Pass an extra Linux kernel command line options,
add a dash `-` separator, and place the options after the dash.
Intended for custom options understood by our `init` scripts,
most of which are prefixed by `lkmc_`, e.g.:
`./run -f 'lkmc_eval="wget google.com" lkmc_lala=y'`
Mnenomic: comes after `-e`.
|`-G` | | Pass extra options to the gem5 executable.
Do not confuse with the arguments passed to config scripts,
like `fs.py`. Example: `./run -G '--help' -g`
|`-g` | | Use gem5 instead of QEMU.
|`-h` | | Show this help message.
|`-I` | | Run with initramfs.
|`-i` | | Run with initrd.
|`-K` | | Use KVM. Only works if guest arch == host arch.
|`-k` | | Enable KGDB.
|`-m` | | Set the memory size of the guest. E.g.: `-m 512M`. Default: `256M`.
|`-x` | | Run in graphic mode. Mnemonic: X11.

|`-m` | |Set the memory size of the guest. E.g.: `-m 512M`. Default: `256M`.
|`-T` | |Enable extra QEMU trace events.
`./configure --enable-trace-backends=simple` seems to enable
some by default, e.g. `pr_manager_run`, and I don't know how to
get rid of them. But those events are rare and should not impact
performance, so we just ignore them for now.
|`-x` | |Run in graphic mode. Mnemonic: X11.
