Guess path to kernel sources using known location of symbol "kernel_init".
Make basepath argument optional.

$ echo 'vfs_open+0x0/0x0' | ./scripts/decode_stacktrace.sh vmlinux ""
vfs_open (home/khlebnikov/src/linux/fs/open.c:912)
After:
$ echo 'vfs_open+0x0/0x0' | ./scripts/decode_stacktrace.sh vmlinux
