Add the required configuration settings to enable kexec in the PVH
variant of xenstore-stubdom. This is required to support live update.
Set the number of kexec module pages to 18 in order to support using
the kexec module memory for the stubdom's 9pfs granted pages.
In Xenstore code test the CONFIG_KEXEC setting in order to determine
whether stubdom live update is supported (PV xenstore-stubdom doesn't
have live update support, as it lacks kexec).

Today the Mini-OS build systems derives libc and lwip config options
from the stubdom and LWIPDIR make variables supplied by the Xen build
system.
In order to prepare those being explicit Mini-OS config options, add
them to the related stubdom Mini-OS config files.
While at it remove the CONFIG_START_NETWORK setting from config files
disabling lwip, as CONFIG_START_NETWORK requires lwip for becoming
effective.
