[PATCH:libpciaccess 1/2] Define PCI_MATCH_ANY as an unsigned int

[Alan Coopersmith]

Clears a bunch of clang warnings of the forms:

common_device_name.c:345:23: warning: comparison of integers of different signs:
 'const uint32_t' (aka 'const unsigned int') and 'int' [-Wsign-compare]
    if ( m->vendor_id == PCI_MATCH_ANY ) {
         ~~~~~~~~~~~~ ^  ~~~~~~~~~~~~~

common_device_name.c:498:19: warning: implicit conversion changes signedness:
 'int' to 'uint32_t' (aka 'unsigned int') [-Wsign-conversion]
    m.device_id = PCI_MATCH_ANY;
                ~ ^~~~~~~~~~~~~
