[LTP] [PATCH 1/2] tst_test.sh: Cleanup getopts usage

[Petr Vorel]

Hi all,

Martin spotted another error in zram01: setup() function in zram01.sh was not
called due being overwritten in zram_lib.sh. Replaced with conditional
expansion.

In case anybody wants to test this latest version is branch
tst_test.sh/cleanup-getopts.fixes in my fork:
https://github.com/pevik/ltp/commits/tst_test.sh/cleanup-getopts.fixes

Kind regards,
Petr
