Vadim Zeitlin 802eac475d Fix undefined behaviour when reading corrupted ZIP files
Don't shift by m_SystemMadeBy value which can potentially be an
arbitrary (8 bit) integer and not necessarily one of the known (and
small) wxZIP_SYSTEM_XXX values, this results in undefined behaviour
whenever this value is greater than 32 or 64 (depending on int size) and
is flagged as such by clang undefined behaviour sanitizer.

To fix the problem, just use a more clear switch statement instead of
using a bit pattern for the lookup, this function is not nearly
performance-sensitive enough to worry about the overhead of the switch
here (assuming it's even slower, in the first place...) and the new
version is much more clear and maintainable.

Credit to OSS-Fuzz: this solves its issue 3792.
