test: remove symlink tests for substitutePath

Although these tests do work right now, they depend on the implementation
of the go command in a way I do not fully understand. The rest of the tests
are sufficient to test the substitutePath implementation as opposed to
how symlinks are interpreted by go or dlv. substitutePath may not be necessary
for all symlinked projects.

For example, when running on darwin:
$ ls ~/go/src/github.com/user/package
 main.go

$ ln -s ~/go/src/github.com/user ~/githubuser/
$ cd ~/githubuser/package; dlv debug
(dlv) sources
~/go/src/github.com/user/package/main.go

If a go.mod file is added into the package in the GOPATH:

$ ls ~/go/src/github.com/user/package
 main.go
 go.mod
$ ln -s ~/go/src/github.com/user ~/githubuser/
$ cd ~/githubuser/package; dlv debug
(dlv) sources
~/githubuser/package/main.go
