The four TESTING/LIN routines currently document ISEED as an
INTEGER array of dimension (4), but their dummy argument
declarations use ISEED(*).
All four routines pass ISEED to CLARND or ZLARND, whose interfaces
require ISEED(4) and document that the fourth element must be odd.
Replace the assumed-size declaration with an explicit size of 4 in
both the commented argument declarations and the actual dummy
argument declarations, so that the source matches the documented
contract and the callee interfaces.
No functional change is intended.
