[PATCH 4/9] tools/nolibc/dirent: avoid errno in readdir_r

[Benjamin Berg]

From: Benjamin Berg <benjamin.b...@intel.com>

Using errno is not possible when NOLIBC_IGNORE_ERRNO is set. Use
sys_lseek instead of lseek as that avoids using errno.

Fixes: 665fa8dea90d ("tools/nolibc: add support for directory access")
