community/retroarch: GNU sed required to disable screensaver

Package Information

• Package name: retroarch
• Package version: 1.19.1-r0
• Alpine version: 3.21.0_alpha20240606
• Alpine architecture: x86_64

Summary

When executing retroarch without GNU sed installed, the following error can be gleaned by executing with verbosity enabled:

[INFO] [X11]: Suspending screensaver (X11, xdg-screensaver).
sed: unterminated {
sh: out of range

When this happens and if you play retroarch using a gamepad, the screensaver will not be suppressed and you will be periodically interrupted by screensaving due to idle mouse/keyboard.

After installing GNU sed, the above sed and sh errors are absent and screensaver suppression is properly enabled.

Steps to reproduce

Without GNU sed, execute retroarch -v, observe the above errors, leave a game running idle, and notice screensaver interruption. Then install GNU sed (apk add sed), execute retroarch -v, observe the absence of above errors, leave a game running idle, and notice that screensaver suppression is working.
