[LTP] [PATCH 5/6] kernel/pt_test: Add missing string.h header

[Petr Vorel]

Fixes implicit declaration of function warnings on older compilers:

pt_test.c: In function ‘intel_pt_pmu_value’:
pt_test.c:67:6: warning: implicit declaration of function ‘strstr’ [-Wimplicit-function-declaration]
  if (strstr(value, delims) == NULL) {
      ^~~~~~
pt_test.c:67:6: warning: incompatible implicit declaration of built-in function ‘strstr’
pt_test.c:67:6: note: include ‘<string.h>’ or provide a declaration of ‘strstr’
pt_test.c:70:3: warning: implicit declaration of function ‘strsep’; did you mean ‘strlen’? [-Wimplicit-function-declaration]
   strsep(&value, delims);
   ^~~~~~
