bugfix: inputs/VegBIEN/: added _no_import to disable import for this folder, since this is actually just an entry in web/datasources/ with VegPath redirection links, rather than an input to the import process. this fixes "schema "VegBIEN" does not exist" errors generated in `make test`.

inputs/input.Makefile: $(dontImport): also support putting a _no_import file at the top level in the datasource to exclude the entire datasource

bugfix: lib/sh/local.sh: removed make() override, which is no longer needed now that its operations are performed by verbosity_compat(), and which caused errors by setting $verbosity to the invalid value ""

bugfix: lib/sh/util.sh: verbosity_compat(): always use default verbosity (`unset verbosity`) when verbosity == 1, regardless of whether the caller has set $verbosity to the special value "", because $verbosity is supposed to be an integer field and "" is not supported by most functions that use $verbosity. in cases where a util.sh script is invoked, it will set $verbosity back to the default value 1, so this will function as before for util.sh scripts and fix $verbosity for scripts that use a different verbosity system.

added inputs/GBIF/raw_occurrence_record_plants/table.tsv.md5

inputs/GBIF/raw_occurrence_record_plants/test.xml.ref: regenerated. updated for new staging table input columns, which are now the same as the output columns.

bugfix: inputs/input.Makefile: %/VegBIEN.csv: use header from map.csv instead of the new columns, so that source.shortname is set to GBIF instead of VegCore

inputs/input.Makefile: %/VegBIEN.csv: when a runscript is available, instead map the output columns of map.csv to VegBIEN, because the columns have been renamed in the staging table

inputs/GBIF/raw_occurrence_record_plants/VegBIEN.csv: regenerated, which adds row_num input col

lib/sh/util.sh: echo_func(): check can_log at beginning of function, so that the resource-intensive func_loc (which calls `readlink -f`) does not need to be called if echo_cmd would not log anything at the current verbosity
