gnu: edirect: Install more programs.

* gnu/packages/bioinformatics.scm (edirect)[arguments]: Add
'patch-programs phase to work around not finding binaries in the PATH.
Rewrite 'install phase to install many more scripts. Rewrite
'wrap-program to wrap more scripts with more programs.
[inputs]: Add edirect-go-programs.
[native-search-paths]: New field.
