all: initialize vhci in linux

* all: initialize vhci in linux

* executor/common_linux.h: improve vhci initialization

* pkg/repro/repro.go: add missing vhci options

* executor/common_linux.h: fix type and add missing header

* executor, pkg: do it like NetInjection

* pkg/csource/csource.go: do not emit syz_emit_vhci if vhci is not enabled

* executor/common_linux.h: fix format string

* executor/common_linux.h: initialize with memset

For som reason {0} gets complains about missing braces...

* executor/common_linux.h: simplify vhci init

* executor/common_linux.h: try to bring all available hci devices up

* executor/common_linux.h: find which hci device has been registered

* executor/common_linux.h: use HCI_VENDOR_PKT response to retrieve device id

* sys/linux/dev_vhci.txt: fix structs of inquiry and report packets

* executor/common_linux.h: remove unnecessary return statement and check vendor_pkt read size

* executor/common_linux.h: remove unnecessary return statement and check vendor_pkt read size

* sys/linux/dev_vhci.txt: pack extended_inquiry_info_t

* sys/linux/l2cap.txt: add l2cap_conf_opt struct

* executor/common_linux.h: just fill bd addr will 0xaa

* executor/common_linux.h: just fill bd addr will 0xaa
