general code cleanup on lbmk shell scripts

in update/blobs/download, i saw instances where
appdir was being deleted with rm -r, but the more
appropriate command would rm -Rf. this is now fixed.

other than that, i've mostly just simplified a bunch
of if statements and consolidated some duplicated
logic (e.g. if/else block for dependencies in
build_dependencies() of update/blobs/download

one or two functions and/or variables have been
renamed, for greater clarity in the code, also
removed a few messages that were redundant

used printf instead of echo, in a few places, also
fixed up the indentation in a few places
