This is a one-line fix to prevent the --preprocess
option (used with --prof-process to output JSON)
to cause an isolate log file profiling process to crash.

`/bin/sh -c` trick wasn't working for several reasons:
* `/bin/sh -c "..."` expects the first argument after `"..."` to be a
`$0`, not a `$1`. Previously `-n` wasn't passed to `nm` because of
this, and many symbols were ordered improperly
* `c++filt` was applied not only to the names of the functions but to
their `nm` prefixes like `t` and `a` (`t xxx` turns into
`unsigned char xxx`).
Instead of applying `c++filt` wide and using `sh -c`, execute `nm` as
requested by `deps/v8/tools/tickprocessor.js` and apply `c++filt` to all
matching entries manually.
Included test demonstrates where previous approach failed: all builtins
were merged into `v8::internal::Builtins::~Builtins`, because they were
prefixed by `t` in `nm` output.

`lib/internal/v8_prof_processor.js` was being excluded from linting, but
the only lint issue it has is that it cannot run in strict mode. Disable
the `strict` rule with a comment and remove the file from
`.eslintignore`.

This change cleans up outstanding comments on #3032. It improves error
handling when no isolate file is provided and adds the --prof-process
flag to the node binary which executes the tick processor on the
provided isolate file.
