Problem description

Hi!

"feat(platform): better glibc detection #537 " breaks musl detection on alpine.

ldd --version returns 1 which will set vim.v.shell_error to 1 and cause the new system() function to fail.

get_libc returns nothing resulting in just Linux_x64 instead of Linux_x64_musl

Detection works in the previous commit.

Expected behavior

detect musl with Linux_x64_musl

Affected packages

*_musl

Ah, it doesn't respect exit code appropriately. #630 should fix this, please reopen if it doesn't!
