thinkpad-acpi: fix module autoloading for older models

Looking at the source, there seems to be a missing * to match my DMI
string.  I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");

While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");

with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")

Note there's no * terminating the string.  As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):

udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAv
