Evan Green ca90bbd410 scripts/decode_stacktrace: Accept dash/underscore in modules ...

The manpage for modprobe mentions that dashes and underscores are
treated interchangeably in module names.  The stack trace dumps seem to
print module names with underscores.  Use bash to replace _ with the
pattern [-_] so that file names with dashes or underscores can be found.

For example, this line:
[   27.919759]  hda_widget_sysfs_init+0x2b8/0x3a5 [snd_hda_core]

should find a module named snd-hda-core.ko.
