t: move 'hex2oct' into test-lib-functions.sh

The helper 'hex2oct' is used to convert base-16 encoded data into a
base-8 binary form, and is useful for preparing data for commands that
accept input in a binary format, such as 'git hash-object', via
'printf'.

This helper is defined identically in three separate places throughout
't'. Move the definition to test-lib-function.sh, so that it can be used
in new test suites, and its definition is not redundant.

This will likewise make our job easier in the subsequent commit, which
also uses 'hex2oct'.
