Target tool build against musl fails, because loff_t is undefined,
despite _GNU_SOURCE being defined.
This is because glibc defines loff_t via <sys/types.h>, but musl defines
loff_t only in fcntl.h and the latter file isn't included beforehand in
imx-usb-loader-target.c.
Add the missing include to <linux/types.h> and include that header in
scripts/common.h to resolve the musl breakage.
This issue was noticedd during a Yocto build against musl, but can be
easily reproduced in Debian as well using the musl-tools package:
export ARCH=sandbox
make HOSTCC=musl-gcc CC=musl-gcc targettools_defconfig
make HOSTCC=musl-gcc CC=musl-gcc
Changes to CI to build sandbox against musl will follow later.
