package/lttng-modules: bump to version 2.13.1

- Add a dependency on kernel >= 3.0:
  88eafb709a
- Add CONFIG_KPROBES to Config.in for kernel >= 5.7:
  a65765406b
- Update license files and their hash because SPDX v3.0 identifiers are
  used since
  b7cdc18250
- This bump will fix a build failure with kernel >= 5.6 thanks to at
  least:
  edfdcb685c
