variable ./mk location, based on user input

when calling ./mk, or from PATH, an absolute path
is created to ./mk

this will likely be different than mk, but it might
be a different script. perhaps the operator is making
a copy of the mk script temporarily - obviously not
advised, no, but here we have a problem because then
lbmk is still running ./mk everywhere

run arg0 instead, now called "mk"

./mk is still hardcoded in release.sh, because we
do need to make sure we're using the right script
there
