tests: Wait longer for hostapd REMOVE command to complete

Some kernel debugging options (especially
CONFIG_DEBUG_KOBJECT_RELEASE=y) can add significant blocking time to
interface removal with NL80211_CMD_DEL_INTERFACE and
SIOCGIFBR(BRCTL_DEL_BRIDGE) block for 1-8 seconds. This could result in
the VLAN test cases failing due to a wpaspy timeout on the REMOVE
command even though the issue was only in the kernel debugging code
making the operations significantly slower. Work around this by using a
longer timeout for that control interface command to allow this type of
debug kernel to be used.
