fcntl.h does not include linux/falloc.h

Solution to issue cannot be found in the documentation.

[X] I checked the documentation.

Issue

On Ubuntu (tested on 20.04 and 22.04):

conda create -n broken-compilers cxx-compiler
conda activate broken-compilers
c++ falloc_test.cpp

where falloc_test.cpp is:

#include <fcntl.h>
#include <iostream>

int main() {
    std::cout << FALLOC_FL_PUNCH_HOLE;
    return 0;
}

outputs:

falloc_test.cpp: In function 'int main()':
falloc_test.cpp:6:18: error: 'FALLOC_FL_PUNCH_HOLE' was not declared in this scope
    6 |     std::cout << FALLOC_FL_PUNCH_HOLE;
      |

Running the exact same command, c++ falloc_test.cpp, outside my conda environment works. Adding #include <linux/falloc.h> also fixes the issue. However, fcntl is supposed to already include this.
