Local Precheck (`make run-precheck`) misses checks when excluding LVS

[amm-efabless]

If you run DISABLE_LVS=1 make run-precheck then it only runs the following specific checks:

license
makefile
default
documentation
consistency
gpio_defines
xor
magic_drc
klayout_feol
klayout_beol
klayout_offgrid
klayout_met_min_ca_density
klayout_pin_label_purposes_overlapping_drawing
klayout_zeroarea

There are extra ones now that it should include, such as illegal_cellname_check.

Is it better to maybe change our Makefile to use --skip_checks and thus exclude LVS (instead of trying to explicitly include everything else) -- or does that option not work this way?

@amm-efabless working on a PR to fix this. Should be done this week per your suggestion.
