lib: Always read SPD sources as text file
Under some circumstances grep detects the input of a spd hex file
as binary resulting in an spd source not beeing added to the
resulting spd.bin. This appears to be especially the case with
heavily commented files.
This commit forces grep to read the input as text file.
Example SPD that would else be detected as binary (regardless
of stripped zero blocks).
