huawei: fix ^SYSINFO parsing

The original sysinfo_parse() in MMBroadbandModemHuawei incorrectly sets
'out_sys_submode_valid' to TRUE even when <sys_submode> is not present
in a ^SYSINFO response. This patch moves the code to
mm-modem-helpers-huawei.c, fixes the regex for parsing ^SYSINFO
responses, and adds unit tests.
