glib-2.0: udpate 2.58.3 -> 2.60.3

Drop autotools-specific parts from patches, as all autotools files
have been removed upstream (meson is now the only option).

Remove autotools-specific 0001-Revert-Use-absolute-paths-in-pkg-config-files.patch

Remove backported fix-nl-abaltmon.patch

Add a hunk to Enable-more-tests-while-cross-compiling.patch which comments out
