build-linux: add support to build kernel modules
Add the kernel module build support into the linux kernel component build
script. The kernel module build can be enabled in the platform's config file by
adding a build config as
LINUX_foo[modules]="true"
where 'foo' is the linux build configuration name. For instance, if 'defconfig'
is the linux build configuration name, the platform config file can enable
module build for defconfig using
LINUX_defconfig[modules]="true"
If kernel module compilation is not required for the build, either mark the
config option as 'false' (LINUX_foo[modules]="false") or do not add this entry
in the platform configuration file.
If kernel module compilation is enabled, the package stage copies the compiled
kernel modules to "output/<platform>/components/linux/modules/"
