configure: make --disable-hsts work

The AC_ARG_ENABLE() macro itself uses a variable called
'enable_[option]', so when our script also used a variable with that
name for the purpose of storing what the user wants, it also
accidentally made it impossible to switch off the feature with
--disable-hsts. Fix this by renaming our variable.
