plf_list: add v2.72, fix a C++98 support regression in v2.70

[valgur]

Adds a fix for mattreecebentley/plf_list#30 to v2.70.

[AbrilRBS]

This should be reported upstream - is_trivially_copyable is >=5 https://godbolt.org/z/chjMvGnb1, but as you pointed out is_always_equal was not added from the LWG 2108 until gcc 6 https://godbolt.org/z/4vxnWEoqn. I wonder if these checks should thus be split! Maybe we can report this upstream

Already did and a fix has been applied upstream: mattreecebentley/plf_list#32 🙂

Thanks for reminding me, though. I bumped the version to include it.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
