test: camera: Remove redundant call of std::string::c_str()

libcamera::File::exists() takes a const reference to a std::string and
clang-tidy's readability-redundant-string-cstr check warns about it:

> ../test/camera/camera_reconfigure.cpp:182:21: warning: redundant call to 'c_str' [readability-redundant-string-cstr]
>                         if (File::exists(pname.c_str())) {
>                                          ^~~~~~~~~~~~~
>                                          pname
