[LTP] [PATCH 1/1] ima_tpm.sh: Check TCONF in ima_boot_aggregate

[Petr Vorel]

This fixes false positive when compiling LTP without openssl headers on
system with TPM 1.2 without evmctl (or old version):

ima_tpm 1 TINFO: verify boot aggregate
ima_tpm 1 TINFO: using command: ima_boot_aggregate -f /sys/kernel/security/tpm0/binary_bios_measurements
tst_test.c:881: TCONF: libcrypto and openssl development packages required
ima_tpm 1 TFAIL: failed to get boot aggregate

For fixing we need to run TCONF in shell, because TCONF from C is not
propagated to shell:
tst_test.c:948: TCONF: libcrypto and openssl development packages required
ima_tpm 1 TCONF: ima_boot_aggregate -f /sys/kernel/security/tpm0/binary_bios_measurements returned TCONF

Fixes: 0f86f185a ("ima_tpm.sh: Fix calculating boot aggregate")
