configure: explicitly disable spirv_compiler 

spirv_compiler is an undeclared variable that was spontaneously
enabled if libshaderc or libglslang were detected, and served as
a way to enable filters.

However, it being undeclared had the effect that it was neither
considered explicitly disabled nor enabled if libshaderc or
libglslang were detected.

The only category we have which explicitly disables variables
is EXTERNAL_LIBRARY_LIST, however, spirv_compiler is not a real
external library, and making it present there would report its
detection on ./configure.

# Unlike other feature flags or libraries, spirv_compiler is not defined
# within any of our predefined categories of components.
# It gets defined if either libshaderc or libglslang check succeeds.
# As such, its in a state of neither being explicitly enabled, nor
# explicitly disabled, but even in this state, being mentioned in
# _deps results in it always passing.
# Disable it explicitly to fix this.
