[LTP] [PATCH] lib/tst_test.sh: Detect quoted parameters correctly

[Xiao Yang]

If we assign "$@" containing quoted parameters to TST_ARGS variable and pass
the variable into getopts, only the first number from quoted parameters can be
processed.  "$@" seems to be treated as an array by default, and declaring
TST_ARGS as an array could fix this issue.

You can reproduce the issue by the folliwng url:
