Subject: [PATCH] CI/Travis: install gperf using package manager (#9325)

Install gperf using package manager instead of building it from source.
When building/installing gperf from source, its install step requires
`texi2pdf` which randomly goes missing on Travis:

    cd doc; /usr/bin/make install
    make[1]: Entering directory '/home/travis/nvim-deps/build/src/gperf/doc'
    cd . && rm -f gperf.aux gperf.toc gperf.cp gperf.fn gperf.ky gperf.pg gperf.tp gperf.vr gperf.log gperf.cps
    cd . && texi2pdf gperf.texi
    /bin/sh: 1: texi2pdf: not found

It's nice to test the "bundled" deps on Travis, but that gets enough
exercise on Windows and macOS, which are the platforms that actually
need "bundled" gperf.
