tools/firmware-utils: mktplinkfw regroup duplicate code

This patch carves out the duplicated code of mktplinfw.c and
mktplinkfw2.c and moves it to mktplinkfw-lib.c

This change is a semantic NOP (the code is unchanged).

To ensure compatibility with gcc-5.x and newer without changing
the code, -fgnu89-inline is added to the build flags for these
two binaries.
