selftests/bpf: Fix pkg-config call on static builds

Browse Source 
For commit b0dcdcb9ae ("resolve_btfids: Fix linker flags detection"),
I suggested setting HOSTPKG_CONFIG to $PKG_CONFIG when compiling
resolve_btfids, but I forgot the quotes around that variable.

As a result, when running vmtest.sh with static linking, it fails as
follows:

    $ LDLIBS=-static PKG_CONFIG='pkg-config --static' ./vmtest.sh
    [...]
    make: unrecognized option '--static'
    Usage: make [options] [target] ...
    [...]

This worked when I tested it because HOSTPKG_CONFIG didn't have a
default value in the resolve_btfids Makefile, but once it does, the
quotes aren't preserved and it fails on the next make call.
