[PATCH] tsm-mr: fix sample dependencies

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The tsm sample fails to link when crypto support is in a loadable module:

ld.lld-22: error: undefined symbol: crypto_alloc_shash
ld.lld-22: error: undefined symbol: crypto_shash_tfm_digest
ld.lld-22: error: undefined symbol: crypto_destroy_tfm
ld.lld-22: error: undefined symbol: crypto_shash_init
ld.lld-22: error: undefined symbol: crypto_shash_finup
>>> referenced by tsm_mr_sample.c
>>>               samples/tsm-mr/tsm_mr_sample.o:(sample_report_extend_mr) in archive vmlinux.a

This used to be handled indirectly by CONFIG_TSM_MEASUREMENTS forcing
the crypto code to be built-in, but that was changed because TSM
itself does not require it.

Move the select into the Kconfig option that controls the sample
instead.

Fixes: f6953f1f9ec4 ("tsm-mr: Add tsm-mr sample code")
Fixes: 44a3873df811 ("coco/guest: Remove unneeded selection of CRYPTO")
