bin/make: moved $make_filter_active test to lib/sh/make.sh make() so that it's also used when make() is run directly (e.g. in a runscript) rather than via the bin/make wrapper in the PATH

bugfix: lib/sh/make.sh: make(): need to match absolute `make` paths such as /usr/bin/make

lib/sh/util.sh: added self_name alias and use it in self/self_sys

lib/sh/util.sh: added sys_cmd_path() and use it in cmd2sys

bugfix: bin/make: use separate $make_filter_active flag instead of $is_outermost for avoiding duplicate output filtering, so that an outer runscript, which sets $is_outermost but does not activate the make filter, will not prevent the make filter from being activated when make is invoked

bugfix: bin/make: need to use sys_cmd instead of command so that the system make command is invoked instead of the wrapper (which would cause infinite mutual recursion for the ~/bien working copy, although not for the ~/Dropbox/svn working copy because nonrecursive=1 was able to remove the single recursion)

bin/make: use .rel to do relative includes

bugfix: lib/sh/util.sh: .rel(): first use realpath() on BASH_SOURCE¹ in case it's a symlink (as it is for bin/make)

inputs/FIA/_src/Makefile: Extraction: $(zips): use $(allZips) containing a zip for each state so that states that have not yet been downloaded and extracted (or had an empty dir created for them) will be downloaded. previously, the extract target only expanded existing zips but did not download new zips unless no zips had yet been downloaded. (this had been necessary because some states do not have a download, and the download of them would be continuously retried every time the Makefile was run.)

bugfix: inputs/FIA/_src/Makefile: `%: %.zip`: if unzip fails because the download does not exist, create an empty dir for the state instead of aborting make
