nongnu: firefor(-esr): Fix Web Speech API.
Firefox loads libspeechd.so.2 during runtime using PR_LoadLibrary and it fails to locate the library in the store. Fix is to add extra phase that patches the file to load the library using an absolute path.
- nongnu/packages/mozilla.scm (firefox-esr) ['patch-SpeechDispatcherService.cpp]: New phase.
Fixes: #284 (closed)
