Restore correct git package for smartos distro

I'm trying to install ruby 2.1.1 on a smartos machine(**SunOS  5.11 joyent i86pc i386 i86pc Solaris**), and it fails when try to check git dependency

the error trace:
```bash
Installing required packages: git...
Error running 'requirements_smartos_libs_install git',

git is not available on the repository
calculating dependencies... done.
nothing to do.
++ return 1
++ return 1
```

the error is because there is not a **git** package on smartos, but scmgit is still available, this is the list i have:

```bash
pkgin search scmgit
scmgit-gitk-1.8.3.1  GIT Tree History Storage Tool (gitk)
scmgit-docs-1.8.3.1  GIT Tree History Storage Tool (documentation)
scmgit-base-1.8.3.1 = GIT Tree History Storage Tool (base package)
scmgit-1.8.3.1       GIT version control suite meta-package
```

and looking on the commits i found this change:
https://github.com/wayneeseguin/rvm/commit/f20e067aa26b3be635f3c951cb3bd0ed2f52d866

the old **'scmgit-base'** package was changed for **'git'** which does exist.

after edit the package name on the smartos script i was able to install 2.1.1
