Update to 1.2.0 release
This commit updates tpm2-tss to version 1.2.0. It also does some cleanups
such as changing the SPEC file permission bits, that were not correct and
renames the project prefix from TPM2.0-TSS to tpm2-tss, that is the name
used in the upstream project now.
tpm2-tss 1.2.0 does not build correctly on Fedora with GCC7, this has been
fixed in tpm2-tss master with commits:
64862cb1f7a0 ("implementation.h: Remove preprocessor magic to selectively enable commands.")
87feb17d81b8 ("implementation.h: Remove preprocessor magic to selectively enable algorithms.")
But those can't be easily cherry picked for 1.2.0, so this commit disables
the GCC7 int-in-bool-context warning instead.
