[PATCH master v2] scripts: include/linux/types.h: define loff_t for musl

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

musl doesn't define loff_t, but glibc does and both of them define
__linux__. This leads to build errors with musl when code makes it into
scripts/ that uses loff_t. This was already fixed once e.g. in commit
c0d065fb0aa0 ("scripts: bareboximd: remove usage of loff_t").

Instead of playing whack-a-mole in future, let's just define loff_t
for non-glibc builds of scripts/.

Also, make sure <linux/types.h> is always included for scripts/common.h,
which is the only header currently making use of loff_t.

Fixes: 5171f4d0696f ("scripts: implement read_fd and pread_full for tools")
