[bug#33186] [PATCH 6/7] gnu: slang: Use a correct location for terminfo dirs.

[Mathieu Othacehe]

As termcap is disabled and no terminfo directory is given, slang is not able
to query terminal capabilities. Specifying a correct path for terminfo will
automatically disable termcap support in the configuration.

* gnu/packages/slang.scm (slang)[source]: Remove the snippet disabling
termcap.
[arguments]: Set MISC_TERMINFO_DIRS to a correct location.
