install_release.sh fails in meson command

**Environment**
- OS: ubuntu 16.04LTS
- scrcpy version: trying to build v2.0 manually
- installation method: install_release.sh
- device model: n/a
- Android version: n/a

**Describe the bug**
Trying to manually build v2.0 as the latest available for my ubuntu 16.04LTS is 1.25

The following steps were done,
- git clone https://github.com/Genymobile/scrcpy
- cd scrcpy
- git checkout tags/v2.0 -b v2.0
- ./install_release.sh

and meson is complaining about `[Errno 2] No such file or directory: '/home/twong/Workspace/open-sources/scrcpy/setup'`

```
$ meson --version
0.29.0
```

```
~/Workspace/open-sources/scrcpy$ ./install_release.sh

Error during basic setup:

[Errno 2] No such file or directory: '/home/twong/Workspace/open-sources/scrcpy/setup'
```

Start with install_release.sh and its Meson build step; compare the v2.0 checkout and installed Meson 0.29.0 with the reported missing setup path. Reproduce the command on the stated environment, then verify that the script completes the client build without the reported Errno 2.
