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.
