blspec: devicetree-overlay: don't warn on multiple delimiting spaces
strsep unlike strtok(_r) returns an empty string for each pair of
consecutive delimiters.
blspec_apply_oftree_overlay is not equipped to handle an empty
string and will attempt treating "abspath/" as device tree file.
Explicitly check for empty strings, so this doesn't happen.
