[linux-lvm] python_lvm_unit.py.in file on v2_02_178 triggered a building error

[Gang He]

Hello List,

For LVM2 for v2_02_178, there is a file python_lvm_unit.py.in under /lvm2/test/api.
in this file, the first line looks like "#!@PYTHON@", I do not know if we should replace this line with "#!/usr/bin/python3"?
Otherwise, there will be a building error, the building log is as below for your reference.

[  117s] This script uses 'env' as an interpreter. For the rpm runtime dependency
[  117s] detection to work, the shebang #!/usr/bin/env python  needs to be patched into
[  117s] #!/usr/bin/python  otherwise the package dependency generator merely adds a
[  117s] dependency on /usr/bin/env rather than the actual interpreter /usr/bin/python.
[  117s] Alternatively, if the file should not be executed, then ensure that it is not
[  117s] marked as executable or don't install it in a path that is reserved for
