  sysdump: rework ignore list code and ignore further files

When getting towards /sys/kernel/tracing, the script is known to hang
at least at the following files:

* /sys/kernel/tracing/trace_pipe
* /sys/kernel/tracing/per_cpu/cpu[0-9]+/trace_pipe
* /sys/kernel/tracing/per_cpu/cpu[0-9]+/trace_pipe_raw
* /sys/kernel/tracing/per_cpu/cpu[0-9]+/snapshot_raw

So we need to extend the list of files to be ignored.

While at it, rework the checks and ignore a bunch of further files, that
can't be read, e.g. due to "Permission denied".

FTR, we sadly can't ignore "/sys/.*/uevent" files globally, as
there are a bunch of files that contain and also provide actual data.

Thanks: Darshaka Patirana for tracking down the /sys/kernel/tracing/* issue
Closes: grml/grml-hwinfo#3

  Log Message:
  -----------
  Provide information to user if sysdump might be hanging

Sometimes new files show up in the kernel and sysdump
might be hanging while reading them. To make this more
visible to the user and how to track this down, provide
information, if not running with -q/-quiet.

  Log Message:
  -----------
  Log 'ip route show table' errors to corresponding error file

We are iterating over the defined tables in /etc/iproute2/rt_tables,
though for tables that don't exist, ip reports an ugly error message,
that's a bit confusing during execution within grml-hwinfo:

| root at grml ~ # grep -v '^#' /etc/iproute2/rt_tables
| 255     local
| 254     main
| 253     default
| 0       unspec
| root at grml ~ # ip route show table 253
| Error: ipv4: FIB table does not exist.
| Dump terminated

Instead, store its error message to an according error file.

  Log Message:
  -----------
  Log efibootmgr errors to efibootmgr.error

On non-UEFI systems, we get an ugly error message:

| root at grml ~ # efibootmgr -v >/dev/null
| Could not parse device path: Invalid argument

Instead log stderr output to efibootmgr.error
