shared: make libmount_parse() non-inline

Back in e2857b3d87306d93f0fba526f3e79f4f6806fb02 I added this function
as static inline in order to avoid linking libmount into libshared.
Nevertheless, a dependency on libmount was added to libbasic in
9e7f941acb0d8fe7a31eec7826ff2c9c6af7044f, and later moved to libshared
in 77c772f227d866331560a8d0487fba12dd128dd4. So the shenanigan with an
inline function is not useful, let's make it a normal function.
