[PATCH] selftests: mqueue|vDSO: fix convert pointer warnings

[Anders Roxell <anders.roxell@linaro.org>]

When building selftests, mqueue and vDSO the following shows up:

warning: passing 'int *' to parameter of type 'unsigned int *' converts between pointers to integer types with different sign [-Wpointer-sign]

warning: passing 'const char *' to parameter of type 'const unsigned char *' converts between pointers to integer types where one is of the unique plain 'char' type and the other is not [-Wpointer-sign]

The code looked OK so what normally are done are, adding the compiler
directive to hide the warnings '-Wno-pointer-sign'.
