tools/vtpm: fix tpm_version.h error during parallel build

Generating the tpm_version.h is not make -j safe:

In file included from ../tpm/tpm_emulator.h:25:0,
                 from ../tpm/tpm_startup.c:18:
../tpm/tpm_version.h:1:0: error: unterminated #ifndef
make[5]: *** [tpm_startup.o] Error 1

Fix this by calling the individual make targets because make can not
know that 'all-recursive' depends on 'version'.
