dev-libs/tree-sitter: stop installing parser.h

There shouldn't be a system-wide copy of parser.h and upstream plan on
dropping this from dev-libs/tree-sitter as it can cause issues if there's
a mismatch between the version used for the bundled generated parser
vs the header used to build the library.

Backport that change to avoid mismatches.
