Eneas U de Queiroz 92379080ea hostapd: adjust patches to work with git am
This adds From:, Date: and Subject: to patches, allowing one to run 'git
am' to import the patches to a hostapd git repository.

From: and Date: fields were taken from the OpenWrt commit where the
patches were first introduced.

Most of the Subject: also followed suit, except for:
 - 300-noscan.patch: Took the description from the LuCI web interface
 - 350-nl80211_del_beacon_bss.patch: Used the file name

The order of the files in the patch was changed to match what git
format-patch does.
