  cmake: move regcomp and futimens checks to "features.h"
  
  In our CMakeLists.txt, we have to check multiple functions in order to
  determine if we have to use our own or whether we can use the
  platform-provided one. For two of these functions, namely `regcomp_l()`
  and `futimens`, the defined macro is actually used inside of the header
  file "src/unix/posix.h". As such, these macros are not only required by
  the library, but also by our test suite, which is makes use of internal
  headers.
  
  To prepare for the CMakeLists.txt split, move these two defines inside
  of the "features.h" header.
