x86: Fix CONFIG_X86_GRUB_SERIAL=""

Browse source 
With

    .config:CONFIG_X86_GRUB_SERIAL=""

which (AFAICT) is the way to tell GRUB not to use a serial console, in

    target/linux/x86/image/Makefile:ifneq ($(CONFIG_X86_GRUB_SERIAL),)

$(CONFIG_X86_GRUB_SERIAL) expands to `""' (a literal double double-quote),
making the condition unconditionally false.

This patch fixes the situation by passing CONFIG_X86_GRUB_SERIAL through
qstrip before testing.
