tpm2-tss: fix build with BR2_FORTIFY_SOURCE_1

Browse Source 
The configure script passes -U FORTIFY_SOURCE -D FORTIFY_SOURCE=2 by
default, which conflicts with BR2_FORTIFY_SOURCE_1 as -Werror is used:

<cross>-gcc ..  -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 .. -D_FORTIFY_SOURCE=1
<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]

Disable this so the FORTIFY_SOURCE flags in TARGET_CFLAGS (if any) is used
instead.
