trace-cmd: Show better data when reporting offsets

After a record, the offset of the CPU data is printed out for
the user to see. This format is not very informative as the
data just says "offset=27f000". Change this to a better
format of:

CPU0 data recorded at offset=0x2d5000
    319488 bytes in size
CPU1 data recorded at offset=0x323000
    258048 bytes in size
CPU2 data recorded at offset=0x362000
    454656 bytes in size
CPU3 data recorded at offset=0x3d1000
    90112 bytes in size
