chromium: disable nodbus

Unfortunately nodbus prevents access to site passwords if they are stored in GNOME Keyring[1]. According to docs chromium can store password in 3 different ways:
GNOME Keyring
KWallet 4
plain text

As KWallet storage may be broken in a same way, using nodbus will force chromium to store passwords in plain text which isn't best option for security and for firejail default.
