zvfs: Remove test for static initialization of stdin, stdout, stderr

This removes a function that created a new mutex and conditional variable
and used memcpy() to compare them with ones in a given fdtable entry.
Since those struct members are initialized statically, this test doesn't
serve much of a purpose anymore. Moreover, padding bytes inside structs
are technically not required to be zero, so these memcpy() calls caused
SonarQube to complain.
