package/igh-ethercat: bump to 1.6.13

This release replaces strncpy() with strscpy() in kernel space, which
fixes the build with Linux >= 7.2, where strncpy() is no longer
available to kernel code.

From:
https://gitlab.com/etherlab.org/ethercat/-/blob/1.6.13/NEWS.md#version-1613

- Made the macb (Cadence GEM) EtherCAT RX path allocation-free to
  avoid receive latency spikes under host memory pressure.
- Included macb in the device driver table and fixed a
  `CONFIG_MACB_USE_HWSTAMP` build issue.
- Use `strscpy` instead of the deprecated `strncpy` in kernel space,
  with a fallback for Linux < 4.2.
- Added a test build for kernel 6.18.
- Improved `ecrt_slave_config_dc()` documentation.
- Adopted the CPPlint configuration of stable-1.7, fixed CPPlint
  complaints and added exceptions for device drivers.
- Use an own pre-commit container with cache in CI.
