ZTS: Simplify some libtest functions

Browse Source 
Don't echo the results of arithmetic expressions, it's not necessary.

Use hw.clockrate sysctl to get CPU freq instead of parsing dmesg.boot
for a line that might not even be there anymore.

Reduce bookkeeping in fill_fs, making it easier to follow.
