Also cleans up past template mistakes made in the 1.4 to 1.6.5
transition:
Remove commented out lines referencing the sqlite database
Remove commented-out do_install override
Remove u_char -> unsigned char sed (u_char still present in source but
upstream fixed build breaks.
reaver-wps-fork-t6x commit 46ccf2e268f7 has the database removal,
d559537b7021 has the u_char fix, and 8977bdf66e43 fixes the destdir
breakage that required the do_install override.
