Fix warning: ‘memset’ used with length equal to number of elements warning

Fix similar warnings to these by including the element size into total size
calculation.

src/pal/tests/palsuite/miscellaneous/SetEnvironmentVariableW/test1/test.cpp: In function ‘int main(int, char**)’:
src/pal/tests/palsuite/miscellaneous/SetEnvironmentVariableW/test1/test.cpp:89:31: warning: ‘memset’ used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
     memset(NewValue,0,BUF_SIZE);
