    pmc: Use isascii(3) to check if a character is ASCII
    
    The previous check did not work on architectures where `char` is
    unsigned as noted by GCC on aarch64:
    
    usr.sbin/pmc/view.cc: In member function 'void pmcview::loadsymboltable(image*, Elf*, Elf_Scn*, GElf_Shdr*)':
    usr.sbin/pmc/view.cc:627:38: error: comparison is always false due to limited range of data type [-Werror=type-limits]
      627 |                         if (fname[i] < 0) {
          |                             ~~~~~~~~~^~~
    
    Reported by:    GCC 15
