[PATCH][TESTBUG] JDK-8214052: Wrong shell used

[Sergey]

Hi,

As stated in the bug description [1] there are few
places in the tests where bash syntax is being used.

First one is (as per ticket):
- vmTestbase/vm/compiler/CodeCacheInfoOnCompilation
I've made a quick fix for that one and patch could be found
inlined below.

Moreover what I've observed is that simple grepping gives me
another test script, that uses bash extensions:
- GeneratePropertyPassword.sh [2]
It seems to be linked with another ticket [3] which is closed,
though it still uses the bash "[[" extension. Perhaps that fix [4]
needs to be reapplied.

In regards to the patch itself, please let me know if I've missed
something. Changes were successfully tested with `dash v0.5.10.2-1`.
