perf(lsp): only joinpath for dirs in watchdirs

Browse Source 
Doesn't have a huge impact, but showed up in profile output using
`require("jit.p").start("i1", "/tmp/profile")`

before:

    31%  joinpath
    25%  fs.lua:0
    13%  normalize
    13%  skip
     8%  _watchfunc
     5%  gsplit
     3%  spairs

after:

    34%  skip
    29%  fs.lua:0
    12%  joinpath
     7%  normalize
     5%  _watchfunc
     5%  spairs
