bluetooth: Arch Linux dbus conf path

[ghost]

Describe the bug
Arch Linux bluez package is built with --with-dbusconfdir=/usr/share but dracut supports config that located only in /etc. This leads to an error:

dracut-install: ERROR: installing '/etc/dbus-1/system.d/bluetooth.conf'
dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.QZNJMz/initramfs -a /etc/bluetooth/main.conf /etc/dbus-1/system.d/bluetooth.conf /var/lib/bluetooth/ /var/lib/bluetooth/E0:D4:64:92:20:83 /var/lib/bluetooth/E0:D4:64:92:20:83/F4:73:35:15:0F:53 /var/lib/bluetooth/E0:D4:64:92:20:83/F4:73:35:15:0F:53/info /var/lib/bluetooth/E0:D4:64:92:20:83/cache /var/lib/bluetooth/E0:D4:64:92:20:83/cache/58:20:59:21:66:23 /var/lib/bluetooth/E0:D4:64:92:20:83/cache/C8:47:8C:C3:95:6E /var/lib/bluetooth/E0:D4:64:92:20:83/cache/F4:73:35:15:0F:53 /var/lib/bluetooth/E0:D4:64:92:20:83/settings

Possible fixes

1. Add support for /usr/share/dbus-1/system.d/bluetooth.conf to bluetooth module:
   

   dracut/modules.d/62bluetooth/module-setup.sh

   Line 72 in f6e6be2

   /etc/dbus-1/system.d/bluetooth.conf \

2. Add an option to override the path in config.

Distribution used
Arch Linux

Dracut version
055

Init system
systemd

To Reproduce
Setup bluetooth keyboard and build initramfs.

Expected behavior
/usr/share/dbus-1/system.d/bluetooth.conf should be installed to initramfs.
