package/slang: fix patch fuzz

Since commit 8f88a64 (support/scripts/apply-patches.sh: set the
maximum fuzz factor to 0), we no longer accept fuzz in patches. Before
8f88a64 was applied, alot of patches were fixed in preparatory
commits, but slang was missed (although the patch has been present since
2017.

Fix the fuzz:
  - leading TABs in Makefile commands
  - fix context
