smcroute: upgrade 2.5.5 -> 2.5.6

Changelog:
==========
- Add smcroutectl batch support, issue openembedded#189. Based on the IPC support added in issue openembedded#185
- Fix openembedded#178: invalid systemd daemon type Simple/Notify vs simple/notify
- Fix openembedded#179: typo in wildcard routes section of README
- Fix openembedded#180: minor typo in file and directory names in documentation
- Fix openembedded#183: casting in IPC code hides error handling of recv()
- Fix openembedded#186: NULL pointer dereference in utimensat() replacement function.
  Found accidentally by Alexey Smirnov. Only triggered on systems that don't
  have a native utimensat() in their C-library, or if you try to build
  SMCRoute without using its own build system ...
- Fix openembedded#187: strange behavior joining/leaving the same group
- Fix openembedded#192: typo in README
