acx-mac80211: use same config options as mac80211 package

Problem was missing CONFIG_MAC80211_DEBUGFS
in the acx-mac80211 build, which broke subsequently the ABI in struct
ieee80211_ops. Defect manifested in failing ieee80211_alloc_hw() and maybe
also in other strange behaviour before.

I added CONFIG_CFG80211_DEBUGFS, CONFIG_MAC80211_DEBUGFS and the same also
for CONFIG_MAC80211_MESH, just to be inline on how it's done currently in
package/mac80211/Makefile.

Thank you Oliver Winker
