Subject: Set `MAKEFLAGS=-j` and `GTEST_BRIEF` in `.envrc`

- Enable parallel builds by default (and allow using environment
  variables to override `make` variables)
  - Hopefully we can get rid of this once we have Meson
- Set `GTEST_BRIEF=1`
  - This only shows failed tests, instead of listing every test on its
    own line.

```
$ GTEST_BRIEF=1 make check
[==========] 328 tests from 15 test suites ran. (37 ms total)
[  PASSED  ] 328 tests.
```
