  [SystemZ][z/OS] Fix error "relative immediate relocation section mismatch"

Constants should go inside the text section, but this is not explicitly coded.
In the test case, the EH table is generated into a PR section. Then the
constant pool of function `fn_with_const_pool()` is emitted, which goes into
the PR section of the EH table insted of the code section. When the constant
is later referenced in the code, the relative offset cannot be calculated
because different sections are involved.
The fix is to explicitly return the text section for constants.
