Subject: [PATCH] sysfs: Fix basename() build with musl

musl provides only standard basename() which accepts non-const string.
This fixes build error with musl C library:

    | sysfs.cc: In function 'std::__cxx11::string sysfs_getbustype(const string&)':
    | sysfs.cc:102:21: error: 'basename' was not declared in this scope
    |        "/devices/" + basename(path.c_str());
    |                      ^~~~~~~~

Upstream-Status: Submitted
