Subject: fix: return boolean from `safeStorage.isEncryptionAvailable()` instead of crashing

On Linux, `isEncryptionAvailable()` was crashing instead of returning a
boolean before the 'ready' event was emitted by the app. The reason of
the crash is that [`CreateKeyStorage()`](https://source.chromium.org/chromium/chromium/src/+/main:components/os_crypt/os_crypt_linux.cc;l=74;drc=35be6215ec8f09e50176f36753c68f26c63d1885;bpv=1;bpt=0)
expects the config to be set but the function responsible for setting the
config, [`SetConfig()`](https://source.chromium.org/chromium/chromium/src/+/main:components/os_crypt/os_crypt_linux.cc;l=237;drc=35be6215ec8f09e50176f36753c68f26c63d1885;bpv=1;bpt=0),
is called only after the app is ready inside [`PostCreateMainMessageLoop()`](https://github.com/electron/electron/blob/main/shell/browser/electron_browser_main_parts.cc#L499).
So this change patches [`IsEncryptionAvailable()`](https://source.chromium.org/chromium/chromium/src/+/main:components/os_crypt/os_crypt_linux.cc;l=245;drc=35be6215ec8f09e50176f36753c68f26c63d1885;bpv=1;bpt=0)
to return false if the config hasn't been set already.
