### What changes were proposed in this pull request?
This PR aims to make `lint-r` exits with non-zero in case of errors. Please note that `lint-r` works correctly when everything are installed correctly.
### Why are the changes needed?
There are two cases which hide errors from Jenkins/AppVeyor/GitHubAction.
1. `lint-r` exits with zero if there is no R installation.
```bash
$ dev/lint-r
dev/lint-r: line 25: type: Rscript: not found
ERROR: You should install R
$ echo $?
0
```
2. `lint-r` exits with zero if we didn't do `R/install-dev.sh`.
```bash
$ dev/lint-r
Error: You should install SparkR in a local directory with `R/install-dev.sh`.
In addition: Warning message:
In library(SparkR, lib.loc = LOCAL_LIB_LOC, logical.return = TRUE) :
no library trees found in 'lib.loc'
Execution halted
lintr checks passed. // <=== Please note here
$ echo $?
0
```
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Manually check the above two cases.

JoshRosen we'd like to check the SparkR source code with the `dev/lint-r` script on the Jenkins. I tried to incorporate the script into `dev/run-test.py`. Could you review it when you have time?
shivaram I modified `dev/lint-r` and `dev/lint-r.R` to install lintr package into a local directory(`R/lib/`) and to exit with a lint status. Could you review it?

Thank Shivaram Venkataraman for your support. This is a prototype script to validate the R files.
