trousers: copy memory in secure way (part 2)

Create tpm_rqu_build_checked to check the size of buffer not to
overflow.

And replace all tpm_rqu_build with this regex rule:
replace this:
tpm_rqu_build\((TPM_ORD([^,)]|\n)*),(([^,)]|\n)*),(([^,)]|\n)*),(([^)]|\n)*)\)
to this:
tpm_rqu_build_checked($1,$3, TSS_TPM_TXBLOB_SIZE,$5,$7)

TEST=Build ok.
TEST=CQ
TEST=manually enroll and login on chell
TEST=run trousers testsuite and had same result before/after this CL.
