ima: defer determining the appraisal hash algorithm for 'ima' template
The same hash algorithm should be used for calculating the file
data hash for the IMA measurement list, as for appraising the file
data integrity. (The appraise hash algorithm is stored in the
'security.ima' extended attribute.) The exception is when the
reference file data hash digest, stored in the extended attribute,
is larger than the one supported by the template. In this case,
the file data hash needs to be calculated twice, once for the
measurement list and, again, for appraisal.
