[PATCH] rt-tests: oslat should use MHz, not Mhz

[Marcelo Tosatti <mtosatti@redhat.com>]

Usage of Mhz, in oslat, is incorrect:

From https://www.nist.gov/pml/owm/writing-si-metric-system-units#:~:text=NOT%20250%20mms.-,Capitalization,the%20beginning%20of%20the%20sentence:

"When the unit is derived from the name of a person, the symbol or the first letter of the symbol is an uppercase letter (W for the unit "watt" or Pa for the unit "pascal")."
