lib/Makefile.inc: fix hex-to-bin conversion of SPD files
This fixes the hex-to-bin conversion command, used to generated binary
SPD files from hexdumps.
An issue that only appeared on one of my systems, where conversion of
'01 02 03' to binary resulted in \x01\x32\x03 instead of \x01\x02\x03:
for c in 01 02 03; do printf $(printf '\%o' 0x$c); done | xxd -g 1
00000000: 01 32 03 .2.
The reason for this was that the syntax in lib/Makefile.inc is wrong,
because the backslash must be escaped due to chaining two printf
commands.
