As Ahmad pointed out in [1], compilation failed if the prepare make
target was not called before compiling the imx-usb-loader, which caused
the generated file not to exist when building for the sandbox target and
broke the build.
As the included utsrelease file only contains a UTS_RELEASE macro
generated from the KERNELVERSION make variable: use the variable
directly and pass it via HOSTCFLAGS as a define. Leave the remaining
code untouched to still support compiling the imx-usb-loader from an
external makefile which does not define the UTS_RELEASE macro.
while at it: also propagate the version number to the target imx-usb-loader.
Fixes: c1b50061f4b3 ("imx-usb-loader: add commandline option for
displaying version number")
