storage: fix build with musl libc
On musl _PATH_MOUNTED is defined in paths.h, not in mntent.h, which causes compilation errors: storage/storage_backend_fs.c: In function 'virStorageBackendFileSystemIsMounted': storage/storage_backend_fs.c:255:23: error: '_PATH_MOUNTED' undeclared (first use in this function); did you mean 'XPATH_POINT'? if ((mtab = fopen(_PATH_MOUNTED, "r")) == NULL) { ^~~~~~~~~~~~~ XPATH_POINT Fix this including paths.h if _PATH_MOUNTED is still not defined after including mntent.h. This also works with glibc and uClibc-ng.
