mesh: Make BSSBasicRateSet configurable

Browse source 
STAs that have different BSSBasicRateSet cannot connect to each other
as per IEEE 802.11s-2011 9.6.0c1:

"A mesh STA shall not establish a mesh peering with a mesh STA using a
different BSSBasicRateSet."

Make BSSBasicRateSet configurable to improve interoperability with other
stations.
