Homogenize default options between FirstBootWizard and lime-defaults

[ilario]

adhoc_ssid in FirstBootWizard code and in lime-defaults-factory should be identical and they are not.
See

lime-packages/packages/first-boot-wizard/files/usr/lib/lua/firstbootwizard.lua

Line 283 in e9efbea

uci_cursor:set("lime-defaults", 'wifi', 'adhoc_ssid', 'LiMe.%H')

and

lime-packages/packages/lime-system/files/etc/config/lime-defaults-factory

Line 57 in 18c8aa5

option adhoc_ssid 'LiMe'

I can see no reason for having that line in FirstBootWizard code (and the next about ieee80211s_mesh_id), deleting it may fix.
Additionally, those two lines could break communities setting a custom adhoc_ssid and ieee80211s_mesh_id in their lime-defaults or network-profiles.

The ssid has been homogenized sometimes in the past.
Anyway there are other settings that look different:

lime-packages/packages/first-boot-wizard/files/usr/lib/lua/firstbootwizard.lua

Line 155 in 606ae4c

uci_cursor:set("wireless", device_name, "mcast_rate", '24000')

lime-packages/packages/lime-system/files/etc/config/lime-defaults

Lines 63 to 66 in 9d9837d

	option adhoc_mcast_rate_2ghz '24000'
	option adhoc_mcast_rate_5ghz '6000'
	option ieee80211s_mcast_rate_2ghz '24000'
	option ieee80211s_mcast_rate_5ghz '6000'

lime-packages/packages/first-boot-wizard/files/usr/lib/lua/firstbootwizard.lua

Line 149 in 606ae4c

uci_cursor:set("wireless", device_name, "distance", '1000')

lime-packages/packages/lime-system/files/etc/config/lime-defaults

Lines 54 to 55 in 9d9837d

	option distance_2ghz '100'
	option distance_5ghz '1000'

Can't FBW just take the values from lime-defaults config file instead of having hardcoded ones?
